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 40 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 60 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
A  20 15 2 30
B 40 35 2 70
C 60 25 4 100


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.


Many students used to ask me how to crack CSIR NET exam easily with minimum effort. Follow simple steps as explained below.

Step-1: Read a reference textbook thoroughly

* Choose a reference textbook from the area in which you are interested.

* Read almost all the topics and get the concept. Solve as many problems as you can from this book. It is very important. Don't neglect this.

* This will create a strong base for you.

Step-2: Study material

* Get study material for some important selected topics which were not covered in the above reference book. Read them like you read the reference book. It is very important to improve your score.

Step-3: Solve questions

* Solve previous year questions from the topics you covered. Neglect questions from other topics you have not covered.

* If you feel the number of topics are not sufficient, then try to read more one by one.

Step-4: Group discussions

* Get involved in group discussions. Try to discuss the concept or questions with your friends OR teachers. If you are shy, it is better to use online forums like AdiChemistry at facebook. You can read what others are posting. You can ask questions and give answers to other's. This will improve your confidence and understanding.

* And last but not least is "highly positive attitude" wins the race.


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.




* How do I prepare for CSIR NET Chemistry exam?/ How to crack this exam?

Very simple. Just think that you can crack CSIR NET chemistry exam. First read a standard textbook of your choice. Choose one from the list given above. Then take the help of study materials with selected topics not covered in the textbook. Finally solve the previous year question papers. That is all.

* 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 Chemistry 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 realization of transaction. 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. It is a self learning module.

* Do you provide study material for part-A of CSIR NET exam?

No. For this, go through books on General Aptitude with emphasis on logical reasoning, graphical analysis, analytical and numerical ability, quantitative comparison, series formation, puzzles etc. 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 now busy with making study material and designing 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 have already landed on the best online coaching center for chemical sciences.

* From where can I freely download CSIR NET & GATE study material in pdf form?

LOL. Do you think it is possible? Those websites with free stuff waste your time and eventually cost your money too by inoculating your system with viruses and trojans.

* 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?
