how to do revision of class 11 while neet preparation???

Class 11 can be revised by going through any notes you yourself have made or provided by your tutors. You can actually revise the NCERT really fast if you have made concepts before.

I would suggest while revision focus on the chapters you don't know too well earlier and try and get the main concepts from which the major questions come from (by referring to the mcqs related to the chapters).

But maker sure you do this with a proper schedule, keep enough days for the chapters you know well. Because you would never want to lose points on them. So for example if you have left atleast X amount of days for the chapters you relatively know, then whenver those many days. You stop focusing on the chapters you don't know too well and shift to the ones you relatively know. So that you score the maximum points.

The reason I say to focus on the chapters you still need to make concepts first, because as time passes it will get difficult to imbibe new material. BUT NEVER COMPROMISE ON THE CHAPTERS YOU KNOW VERY WELL BY NOT REVISING THEM OVER NEW CHAPTERS YOU STILL NEED TO WORK TO MAKE CONCEPTS.

SOLVE MCQS.

In order to revise the syllabus of 11th class for NEET preparation you can take help of your notes, flashcards. Put extra effort in revising important topics. You can also solve MCQs related to them. So, you can grasp the topics. You can go through mock test series to analyze your preparation level and to know your strength and weakness.

All the Best!!
