sir ,i m starting revision ,please guide me how to start ?

in my suggestion pinky just go through the formulas and concepts, and try solving 2-3 question on each formula or concept revised.specialy in chemistry revise organic chemistry mechanism.

this study plan works excelent if u studied in ur past very well and just need to revise only literally.

well all the best

start with mathematics and be thorough in physics and chemistry as they lay your foundation for your marks
