It’s time more to test yourself rather than learning new topics.

For the first 5 days, complete all the left overs or revision left. 

Day 6- Take test in the morning.(3 hr) , next for 1 hour choke out the mistakes, then for next 2 hours revise Biology. 

Afternoon- Do MCQs from Physics and Chemistry.

Night- After 7 pm. Take another test, After 10 pm revise the mistakes.

Next Day - No tests. Revise Bio, Chemistry, Physics according to your convenience.

Next Day- Follow the test schedule again.

Do this for alternate days.

The last day do not study only relax. Best of Luck !
