Hi Aspirant!

It would be a most difficult task for you, but if you are asking to prepare for physics in one day. Then I would suggest you to first check out the complete syllabus , pick up those topics which weigh more in the exam. And one more thing, it is probably impossible to score good marks by preparing only one day if you do not have good hand over the fundamentals/concepts. Find out a friend who has good detailed notes on those topics which weigh more, go through them thoroughly. Once done, pick up previous years question papers, solve them you will find many questions repeating in almost every year's exam. Once you are done with all these things, give a final revision to all the topics and you are ready.

Hope I answered your query, thankyou!
