Tips for JEE Main chemistry 2021:

JEE Main chemistry section is considered the most fruitful section in obtaining good marks in comparison to physics and mathematics. It requires a lot of practice of chemical equations, bonds and numerical. One should make a habit of learning by writing the equations as frequently as possible because they cannot be remembered orally.

It is considered as the rank deciding subject in most competitive exams because it comprises mostly theoretical based questions in comparison to physics and mathematics and so it is also the most scoring subject. The main strategy to score well is to analyse previous year JEE Main question papers and strengthen the topics which have mostly occurred. To make the study process more efficient you can check your performance through online test series which are based on the exam pattern. There are 15-18 tests papers for JEE Mains and 9-10 tests papers of JEE Advance, after giving tests you will get your performance report which will help you find your area of improvements and your speed.

This section deals with the understanding and observing of the physical and chemical properties of different matter around us. It covers 40% of the JEE Main Chemistry paper and includes the basic concepts and formulae. A good tip is to make detailed notes on each topic and avoid skipping regular practice to crack these numerical questions.

Some important concepts in physical chemistry are:

  1. Mole concept

  2. Equilibrium

  3. Atomic structure

  4. Chemical Bonding

  1. Organic Chemistry:

It might seem difficult at first, but you can master this part with regular studying. The more you remember the reactions, structures and compounds thoroughly, the better. Do you know you can actually attempt this section in just 20 minutes if studied well? The trick would be to understand the fundamentals and mechanisms rather than learning by heart. Don't forget to make notes on the important topics and keep revising them every week.

Some important sub-topics for chemistry are:

  1. Hydrocarbons

  2. Organic compounds containing Halogens, Oxygens, Nitrogen

  3. Purification and Characterization of Organic Compounds.

  4. Nomenclature

  5. Polymers

  6. Chemistry in Everyday Life

  1. Inorganic Chemistry:

This is relatively much easier than any other section and doesn’t include any problem-solving questions. Therefore, this is a very time-saving section. Moreover, it contains very simple and straightforward questions that you can easily cover from NCERT XI and XII books.

Study the methods of preparation, uses, chemical reactions of compounds thoroughly as they are the important topics and cannot be missed.

Some important sun-topics in inorganic chemistry are:

  1. Coordination Compounds

  2. Classification of Elements and Periodicity in Properties

  3. s-block elements (Alkali and Alkaline earth)

  4. p-block elements

  5. d and f block elements

  6. Hydrogen

Practise conversions and reagents daily along with chemical reactions and their mechanisms. Daily practise and revision will help you make your mind stronger until JEE Main Exam.

With the right procedures, you can crack this hard nut without fail. You simply need to have self-confidence and keep practising via mock exams, which are extremely helpful. Remember, that this is the paper that can bring you the maximum scores, so do it well.

Hey can please someone tell me with what jee mains percentile can I get aiml in cbit or vnr vjiet. I have a bc-e certificate, an ews one and home state

With a BC-E category certificate, EWS certificate, and Telangana home-state quota, your chances of getting admission to AIML or related CSE branches in CBIT, VNR VJIET, or similar top private colleges in Telangana depend mainly on your JEE Main percentile and the TS EAMCET counselling process, because these colleges fill seats through both TS EAMCET ranks and JEE Main scores (Category-B seats).

For Category-A seats (through TS EAMCET), JEE Main percentile is not considered. Admission is purely based on your TS EAMCET rank, reservation category, gender, and home-state status. CBIT and VNR are highly competitive, especially for AIML, CSE, and IT branches, so you generally need a very strong TS EAMCET rank (usually within a few thousand for BC-E candidates, sometimes slightly relaxed for girls).

For Category-B seats (JEE Main quota), JEE Main percentile matters. Based on recent trends, to have a realistic chance:

  • For CBIT (AIML / CSE / IT), a JEE Main percentile of around 95+ is usually expected, even for reserved categories, because Category-B seats are limited and competition is high.

  • For VNR VJIET (AIML / CSE / IT), candidates with 92–95 percentile sometimes have chances, depending on availability and the specific branch.

  • If your percentile is below 90, getting AIML or core CSE in CBIT or VNR becomes difficult, but you may still have chances in slightly lower-demand branches (like ECE, EEE, or emerging specialisations) or in other good private colleges affiliated with JNTU or autonomous institutions.

Your BC-E and EWS certificates do help mainly in TS EAMCET counselling (Category-A seats), not significantly in Category-B (JEE Main) admissions, where merit largely dominates. Home-state status is already assumed for these colleges, so there is no extra advantage beyond eligibility.

In summary, if your JEE Main percentile is 95 or above, you can reasonably target AIML/CSE in VNR and possibly CBIT through Category-B. If it is 90–94, VNR or related branches are more realistic than CBIT. Below that, it is better to focus on TS EAMCET performance or consider other reputed Telangana colleges offering AIML. If you want, you can share your exact JEE Main percentile and TS EAMCET rank, and I can give you a more precise college- and branch-wise estimate.
