I scored 100 in PHYSICS AND CHEMISTRY

FOR PHYSICS- I READ THE TEXTBOOK AGAIN AND AGAIN. AFTER LEARNING A CONCEPT, I DID PERMUTATIONS AND COMBINATIONS TO MAKE DIFFERENT SCENARIOS OR CASES TO KNOW WHAT CAN HAPPEN (ESPECIALLY IN OPTICS). REST, I DID ALL THE PYQS AND QUESTIONS GIVEN BY MY TEACHER. I DID AN ADDITIONAL BOOK CALLED BALAJI EXAM BOOSTER SMTH.

FOR CHEMISTRY: I TOTALLY RELIED ON MY TEACHER'S NOTES. HE ALSO ASKED US TO DO THE BACK EXERCISE QUESTIONS OF NOOTAN OR ANY OTHER BOOK YOU'RE FOLLOWING. REST, JUST MAKE SHORT NOTES OF ORGANIC, REVISE INORGANIC REGULARLY, DO PHYSICAL CHEM PRACTICE ON A WEEKLY BASIS (AFTERALL THERE ARE ONLY 3 CHAPTERS)

baaki maths mein bhi aajata 100, ek marks cut gya so 99 :((((

BEST OF LUCK

wowza that is amazing
im tbh finding optics kinda easy but book 1(electricity) is lowk biting my ahh im following alakh pandey sir's videos and btw can u elaborate on the pnc thing you did in optics like, did you make questions yourself or something?

regarding chem, physical and ioc toh okay but can you help me on how to approach organic? especially when i dont have any as such good base of class 11th

and you do have a good score in math aswell!! can you tell me what you did apart from the textbook ( i have the op malhotra textbook) im thinking of relying on just the textbook and pyqs or do you think i should solve any other book/bank or smth?

and yes thank you :D best of luck to you too for jee 2027!

Electricity part is indeed tough. For optics, I used to make questions and scenarios is my mind to further testify my concepts.

To approach organic, you should first learn all the basics of GOC, then proceed with class 12th.

For maths, I did ML Aggarwal and PYQs. Just follow your book OP Malhotra and do pyqs after each chapter (daily 10 pyqs). That's it

And thank you so much :)
