CBSE 12th

Great choice Anisha and a fabulous goal with aims comes sacrifice and with goals comes persistence and with target comes desire. In order to achieve your goal, you should give more and more time on revisions and dealing with important derivatives of physics solving past 10 years question papers
for biology going through the text again and again improving, your speed and presentation of your hand writing improving the speed of making diagrams clean and neat for chemistry revising important reactions dealing with frequently asked questions in past years and writing down everyday. Keep revising for language keep in reading the chapters and grammar again and again. Keep on practicing the unseen passages and seen passages of the book avoiding TV and limiting the food, drinking water, during revising meditating atleast 3 times a week. Taking a note of your progress, every Sunday morning and talking about your plan with only your parents or not even them and surprises them.
All the best and I wish you a very happy new year.
