GIVE ME AN IDEA FOR LAST ONE MONTH REVISION / PREPARATION FOR NEET

Last month revision is for sure crucial for your neet preparations, as it can affect your Score by huge margin.
Starting with Biology, along with Ncert, one is required to even solve Ncert based one liner questions. Questions are always a best and quicker way to revise any topic. For Chemistry and physics, concept and formula based problems are must to do. No need for trying tough questions, now it's time to sharpen the old concepts in quick succession.
All the Very best..

If you are planning to revise everything then try to revise the topics you find difficult first as that'll take up more time and the easy topics you can just give a passing glance in the end.
Also make a list of stuff that is usually crammed ( names and important data) so that you can look through it in the end.
Revise biology as that has the most stuff to be remembered. Chemistry and physics have more concepts which would be clear by now.
Give yourself one day of rest before the exam to refresh your mind. Do have a good night's sleep the night before.
Good luck!

Clear your basic concepts solve previous years questions as much as you can.
