Hi reader ,

the most efficient way to revise the whole syllabus of a subject is by solving the previous year questions. since your syllabus of BIOLOGY is going to be completed on 20th february , you should shift your focus on solving pyqs  multiple times , this way you'll figure out the area which you are not able to revise/recall quickly and then you can turn your focus on your weak areas.

never leave a chapter looking at any random blueprint of the paper or based on previous trends. you never know from which chapter maximum questions may be asked.

never try to study whole night a day before exam. you need optimum sleep to achieve your aim.

make a daily schedule and try to devote some time to each subject.

for physics make a formula sheet so that you can revisit them quickly whenever you feel like forgetting them.

i hope this helps

thank you
