How do I revise in the last month for JEE Mains if I am aiming for a score above 300? Ps: I am a dropper.

Do Not Learn Anything New
Your revision time should be used to literally redo previous work done, regarding subject topics and be thorough with what you've already learnt. Learning something new may also weaken your confidence at this point.

Go through Revision Notes and Flashcards
This is the ideal time to go through your previously prepared notes. This process helps to strengthen concepts in your memory and therefore applying them becomes easier. If you have not prepared flashcards, do not waste time in preparing them now. Although flashcards would've made it easier for recollection, your notes will also suffice.

Practice!
Practice application based questions from previous papers as much as possible. You can switch between the following types of topics
Topics you are strong at- Helps to gain momentum
Important Topics- Refer previous year papers
Hard Topics
Other Topics

Mock Tests
Do not forget to attempt sample mock tests. These tests should be attempted for know how to manage time and pressure of the actual examination. Therefore, you should set conditions as ideal to the actual situation with no distractions.

Prepare a schedule/ timetable
Prepare a schedule or ask a mentor to prepare one for you. Schedule all your breaks, sleep cycle and study time in this timetable and make sure you stick to it. Set goals and include it as part of your schedule. The goals you set can be daily or weekly depending on your comfort. Set appropriate time limits to practice questions and ensure that this skill helps in time management during the actual JEE exam.

JEE Main score of 300+ is considered as outstanding and it requires a lot of hard work.

Below there are some tips to score 300+ in JEE Main

Concepts should be crystal clear in your mind. If you are going to start preparation now from zero level do it thoroughly. Don't get discouraged if you don't really have a lot of time in your hand. It's possible. Students have managed to score marks close to 320 with just 3 months in hand.

2. Selection of Books

The books you select for your reference will either make things easy for you or difficult. A lot of authors and books have emerged in recent times bu we suggest the following:

1. DC Pandey and H C Verma are enough to build concepts in Physics.

2. SK Goyal would be ideal for Maths (Algebra). Maths is a scoring subject and if you are referring to this book, you can easily score around 80% here.

NCERT, however will still remain your primary reference book and that cannot be ignored out overlooked whatsoever.

3. Concentration

Concentration has a lot to do with your efficiency. If you are productive, you will be able to do more things in less time.

4. Self Study

Self study is by far the most important factor because of the following:

You should be spending your academic time in three things:

Absorption of concepts (i.e learning concepts)
Application of concepts (i.e problem solving)
Analysis

However, you spend time 90% of the time in absorbing concepts , 10% time in application of concepts and absolutely no time for analysis.

So you need to start balancing these three things out

ALL THE BEST!!
