Firstly, time is limited so get to work and keep all electronic gadgets away.
- Give chapters a read, atleast two daily and solve NEET level questions for those two chapters that day ( how many ever possible) . This is only possible if you know something about the chapters from beforehand. In this way you can revise the physics syllabus in about 15 days. Then the rest of the days practise amazing number of MCQs and solve past years papers.
- If you meant starting from scratch, better strenthen your Biology and Chemistry and learn some basic formulas and their application from most of the chapters of Physics. Dont forget doing past years questions as questions are quite repititive in NEET.
Hope this helps
