Welcome. Good news to chemistry students, who have a strong desire to pursue their dream research with a scholarship at prestigious institutions of India. I launched this web page to help the aspirants who wish to crack CSIR NET & GATE exams in chemical sciences.
On this page, you can find CSIR NET & GATE chemistry study material including selective solved questions from some of previous year question papers, that help in preparation and makes your life easy.
Most of you do not have timely access to standard textbooks or lost in your busy schedule and search for a helping hand. So I decided to provide you with an indispensable chemistry study material to make you stress free. It is the best substitute for costly notes and long hours of coaching.
Recently I launched a new page for online coaching which is free for a while. It is still in the beta stage.
NOTE: Above study material is of very high standards unlike cut, copy & paste type of notes provided by other institutes. Hence the prices are according to the standards maintained.
Dear Adi Sir,
I am very thankful to you as I have cleared the CSIR NET with 43 AIR (Roll No.140835) in June 2014 and qualified GATE 2014 in with the help of your notes.

CSIR UGC COMBINED NATIONAL ELIGIBILITY TEST (CSIR UGC NET) for RESEARCH FELLOWSHIP & LECTURESHIP for chemical sciences is conducted twice every year (in June & in December) to select right candidates to award research fellowships, initially for two years (JRF) which can be further extended for three more years (SRF). This exam is also popularly known as CSIR NET or CSIR UGC NET exam. Most of the admissions into Ph.D courses in prestigious institutions of India like IISc, Central University of Hyderabad, IIT's and several CSIR laboratories require the qualification in CSIR UGC NET exam.
According to new pattern implemented from June 2011 onwards, the CSIR NET exam in chemical sciences is:
* a single paper test having multiple choice questions (MCQs)
* carries a maximum of 200 marks.
* is divided into three parts (A, B & C).
* conducted for the duration of 3 hours.
Part - A carries 20 questions and is common to all the subjects. The candidate is required to answer any 15 questions. Each correct answer is awarded with 2 marks. The total marks allocated to this section shall be 30 out of 200.
The revised pattern for this part will test general aptitude with emphasis on logical reasoning, graphical analysis, analytical and numerical ability, quantitative comparison, series formation, puzzles etc. There is no syllabus prescribed for this.
Part - B contains 50 multiple choice questions generally covering the topics given in the syllabus. A candidate is required to answer any 35 questions and each correct answer is awarded with 2 marks. The total marks allocated to this section shall be 70 out of 200.
The standards of these questions from this section may range from 10+2 to PG level in chemistry subject.
Part - C consists of 75 questions. A candidate shall be required to answer any 25 questions, each carrying 4 marks. The maximum marks allocated to this section is 100 out of 200.
The questions shall be of analytical nature where a candidate is expected to apply the scientific knowledge in chemistry to arrive at the solution to the given problem.
There will be negative marking @25% for each wrong answer.
|Part||# of questions||To be attempted||Marks allotted per each question||Maximum marks|
Cutoff marks for previous CSIR NET exams in chemical sciences paper are tabulated below. Note that these are percentages and are not same for each exam. Multiply with 2 to get actual score per 200. CSIR never announced the criteria for deciding the cutoff marks. They never announced them before exam too. So no guess work please.
|% Cutoff marks for Chemical sciences|
Month & Year of Exam
|Junior Research Fellowship
* June, 2013 cuttoff marks were not announced by CSIR officially. I got them from various sources. I cannot guarantee the validity of above data. Please confirm with CSIR before coming to a conclusion.
** From Dec, 2014 onwards, CSIR started announcing seperate cutoff for OBC.
*** From June, 2015 onwards, CSIR started announcing seperate cutoff for PH & VH.
As is evident from above data, I am expecting further increase in the cutoff marks for future exams.
GATE exam is conducted once in every year in chemical sciences along with other engineering subjects. It is organized by IIT's and the purpose of this exam is to select candidates who want to pursue their masters courses in technology (M. Tech). The candidates with very good GATE score are also eligible to get the CSIR scholarship in some selected institutes and preferred over others while taking into project work.
The syllabus for CSIR NET and GATE exams including other exams for Ph.D entrance exams is almost same. The common syllabus for both part B & C of CSIR NET exam in chemical sciences is given below.

Most common question asked by students is "What should be the plan of action to crack CSIR NET exam?" or "How should I prepare for this exam?".
My sincere, but very simple, suggestion is to read standard textbooks (see the list of suggested textbooks) and solve old question papers of CSIR, GATE, IISc etc. If you are already done with reading lots of classroom notes and other textbooks then start with solving old question papers. This is the best way to crack any exam.
What should be the plan of action?
For Part-A, one can go through books on General Aptitude and Logical Reasoning.
For Part-B, you need to be thorough in all the areas of chemistry from 10+2 level to undergraduate level. Everything is important here.
For Part-C, choose any area of chemical sciences i.e, either organic or inorganic or physical, depending on your taste and specialization at PG level.
Always choose right books and solve the previous question papers in a logical manner.
Few pupil are also asking for important topics/books, mostly for Paper-C. Following is a possible combination of topics/books you can choose.
Books on General Aptitude & logical reasoning
|10+2 NCERT Chemistry textbooks
undergraduate level chemistry books
IF YOU STILL HAVE QUESTIONS RELATED TO PREPARATION PLEASE GO THROUGH THE FREQUENTLY ASKED QUESTIONS SECTION.
The best suggestion to crack any exam is to go through the textbooks written by authorities in the respective fields. Following is a list of textbooks in different areas of chemical sciences. Actual list is very vast. However, it is better to go through only few books that are followed by professors at our universities and IITs.
1) Inorganic chemistry by Shriver & Atkins (Suggested by most of Indian Institutues of Technology. Solve the exercises given inside and at the end of each chapter to master this subject.)
2) Inorganic chemistry by Catherine E. Housecroft (Another favorite of IIT professors. The NCERT chemistry textbooks have the material referenced from this book.)
3) Inorganic chemistry by Miessler (I like this book for its simple and straight forward explanation.)
4) Inorganic chemistry: Principles of structure and reactivity by James E. Huheey (You will start appreciating inorganic chemistry after reading this book. I enjoyed and learned a lot from this fantastic text book.)
5) Advanced inorganic chemistry by F. Albert Cotton & Geoffrey Wilkinson (Must for an inorganic chemist. But you need lots of patience to feel like a Jargon.)
6) The organometallic chemistry of the transition metals by Robert H. Crabtree
7) NMR, NQR, EPR & MOSSBAUER Spectroscopy in inorganic chemistry by R.V.Parish
8) Biological inorganic chemistry: An introduction by Robert R.Chrichton
9) Bioinorganic chemistry: A short course by Rosette M. Roat-Malone
1) Organic chemistry by Clayden, Greeves, Warren & Wothers (I think already you know about this famous book. Not only written in a lucid manner and is very important for those who dare to attempt organic questions from part C of CSIR NET exam. Most of the previous organic questions are straightly from this book. Just enjoy reading this book and earn easy points.)
2) Modern methods of organic synthesis by William Carruthers & Iain Coldham (Refer this book for advanced organic synthesis. Another book from which most of the organic questions are dumped into the exam.)
3) Organic chemistry by John McMurry (Must read for basics. Very famous undergraduate book.)
4) Organic chemistry by L.G.Wade, JR (Another book for basics)
5) Advanced organic chemistry by J March (A must reference book)
6) Pericyclic reactions by Ian Fleming
7) Modern organic synthesis: An introduction by Michael H. Nantz (Another good book with straight forward explanations)
8) Spectrometric identification of organic compounds by Robert M. Silverstein
9) Introduction to organic photochemistry by John D. Coyle
10) Advanced organic chemistry (Part A & B) by Francis A. Carey & Richard J. Sundberg (Another reference book for organic synthesis)
11) Named organic reactions by Thomas laue & Andreas Plagens
1) Physical chemistry by P.W. Atkins & Julio De Paula (Read the book. Solve the exercises & problems given. That is sufficient.)
2) Physical chemistry by Ira N. Levine
3) Physical chemistry by Robert G. Mortimer
* How do I prepare for CSIR NET Chemistry exam?/ How to crack this exam?
Already this is discussed. Please go through the section: Plan of action for CSIR NET exam.
* I did my M.Sc long back. I forgot most of the subject. How do I start my preparation for NET exam?
No problem. That is actually good. You are now free from effects of conventional methods of studying.
You can start reading standard text books again and simultaneously solve the previous year question papers. You can join adichemistry forum to discuss your problems and also learn the subject.
* What are the important topics for CSIR NET / GATE chemical sciences exams?
It depends on your choice of branch of chemistry in which you are interested. This subject was already discussed. See the section: Plan of action for CSIR NET exam.
* Is it possible to crack CSIR UGC NET exam without coaching?
Yes. It is possible. You have to spend some time and invest it wisely. You need to do smart work. Go through suggested textbooks and solve previous year question papers.
I am here to help you by providing the study material (both free and paid) and suggestions through group discussions.
You can join my chemistry forum and get more information freely. There are about more than 2000 questions discussed on this forum. All is free here.
* I would like to know, whether do you provide complete study material or not?
No. At present, the chemistry study material is not yet complete. However, it helps you in cracking the CSIR NET exam and makes your life easy.
Though it is not complete, I touched most of the important and selected topics and I am constantly updating the material.
Especially, I am providing topic wise solved questions of previous year CSIR, GATE, IISc and other exams.
Actually, I put this study material for selling only after it reached certain volume and myself satisfied that it is sufficient to reach the target/cutoff marks if used properly in a logical manner. I expect you to read at least one suggested text book from your area of interest thoroughly along with this study material. Don't take the literal meaning here. Read the sentences carefully and decide yourself. If unable to follow or still confused, drop me a mail.
* Do you provide solved previous year question papers of CSIR NET or GATE exams?
The answer is both NO and YES.
NO because I am not providing the solved question papers as they are.
YES because I am providing you with the topic wise solved questions. There is some reorganization of questions from previous year CSIR & GATE papers. For example, you will find all organic chemistry questions at one place. Each question is provided with: key, thorough explanation as well as, in most cases, follow up questions.
* How do I purchase CSIR NET chemical sciences study material?
You can pay me by remitting the requisite amount into my bank account either at your nearest branch or through NEFT. You will get the downloading links to study material immediately after confirmation of payment into my account. It may take just few minutes to few hours, though not always, to get the softcopy of study material depending on the method of payment, time taken for the bank to transfer the funds and the time taken for confirmation from my side. You should inform me the details of payment immediately so that I can process your order quickly. For more details you can mail me at:
* Do you send hardcopy of CSIR UGC NET study material to my address?
No. At present I am only providing you with the soft copy, which you can download and take printouts.
* Why don't you provide this material in hard copy so that it will be available cheaper and most of the poor students can purchase?
Hmm. Then throw it into the dust bin?
Yes. I know that it is a lot cheaper if I arrange the hardcopy. However there are three reasons for not doing so.
1) The material is not yet complete. I am providing very high standard and carefully written study material. It is not cut/copy and paste material just like that is provided by most of the coaching centers. It takes more time to prepare one topic.
2) This material is going to be updated constantly. Therefore you will miss new updates if you purchase hard copy.
3) Last but very important argument is: I have seen most of the students do not use it at all, if there is no interaction with the teacher and proper guidance. Previously, when I have given this material freely, I found most of the students downloaded to never use it. Some of them actually misused and distributed the copies on the net without my permission.
Let me explain what are the benefits of soft copy. The online versions are very easy to modify and hence you can get updates. You can also come into interaction with more people in the forums so that you can discuss the problems and get involved in the study seriously.
However I will publish this material as soon as I feel it is sufficient enough to do so.
* I am poor. May I get CSIR NET chemical sciences study material freely?
* How can I trust you and your study material? How do you assure me that you will send the material after payment?
Hmm. Yes this is indeed a good question. The problem is I cannot give assurance online. LOL! I think no one can do that. But regarding the standards of my study material, you can justify yourself by going through the sample copies.
However if you want to know what is my credibility; try my online coaching and also visit my facebook profile and forum. Then take a decision.
Actually I am doing service here and not a greedy business. I am selling this stuff to do more service. Why should I want to lose my credibility by cheating you? Previously I used to give this material freely and there are more than 5000 students who got the benefit from my forums, online study material etc. But now I am selling this to run the website and in making notes. After all, who will give me their free time to digitalize my madness. Do you?
* Do you give online coaching?
Yes. I have launched this service recently. You can try this service at: CSIR NET Chemistry Online Coaching.
* Do you have study material for general science section (part-A) of CSIR NET exam?
No. However, the syllabus for Part-A is revised. So now there is no need of this. You should go through books on General Aptitude with emphasis on logical reasoning, graphical analysis, analytical and numerical ability, quantitative comparison, series formation, puzzles etc., for part-A. These are available from the market.
* Who are you? Where do you live? Have you ever qualified for NET exam? etc. etc.
I am Aditya vardhan, lecturer in chemistry - living and working at Warangal, Telangana, India. I already cracked CSIR NET exam in 1995 and got JRF + LS. I launched this website to help students who wish to clear NET exam.
* Do you provide coaching at your home town?
No. I am happy with my 10+2 level students. It is my passion that forced me to publish this material through Adichemistry website.
* What are the best CSIR chemistry or UGC NET coaching centers in Delhi, Hyderabad, Bangalore, Pune, Bombay, Culcutta, Chennai .......?
Sorry. I do not know. But you already landed on the best online coaching center for chemical sciences.
* I want to talk to you. What is your mobile number?
Sorry. I do not like to communicate through mobile. It consumes lots of time. And most of the time, I will be in the class room or busy in learning chemistry. However you can speak to me more conveniently through e-mail.
* I do not find my question here. What do I do?
