Hello aspirant,

If you have a small knowledge about the Topics and if you have attend few classes (i.e, important topics classes) 

Start with magnetism and go through communication system,atoms, wave optics ,electomagnetic waves and all

2hrs 1 topic if you prepare then you can get 75 % marks 

Hope above information is helpful to you

Thank you

Dear Ria

Ria the stratige should be simple , accurate and to the point such that with the two days tenure of time you can be able to revise all your syllabus as well before the exam, do the previous year Physics paper rather than model paper such that you can go through with the pattern in which you will going to answer the questions in that and inorder to go through with the stratigies for the preparation of the two you need to revise the formulas first and then go with your short notes which you have prepared while your preparation and kindly do not go with the new topics on those days.

All the best
