Hello,
Chemistry is perhaps the 2nd most scoring subject for most of the aspirants. The strategy must be to both clear concepts and practice MCQs. This is often repeated and often forgotten too. As always, remember that your base book is NCERT. Be thorough with every single point in it. Stress it enough. Direct NCERT questions are asked in NCERT nowadays, so practice NCERT oneliners. Let us look at individual parts of chemistry
Physical: the formula and the basic numerical application is enough. It's perhaps the easiest part of them. Keep on revising the chapters and solving questions as well. Practice NEET previous years' questions for reference. Inorganic: heavily rote based (at least in medical entrances) and perhaps the branch where your brain is used the least ( cognitive aspect ). Regular efforts are must. Else failure is sure. Organic: earlier used to be a piece of cake but not anymore. Start solving JEE Mains papers, any standard reference book or coaching material to gain an edge. Organic can be conquered only by practice of mechanism based questions. Practice, practice till you get perfect. Thanks.
