stop preparing for 100th rank prepare as you want good marks good knowledge beacuse byhearting also leads to 100th rank but after the admission into iits and nits you will face difficulties in studies so go with concept

Yes, surely you can succeed. If you have spirit now and can maintain the same for whole year without any distractions you can. Getting rank under 100 in jee advance is very tough. So start preparing well and never get demotivated. Hardwork pays off. Only think you can and you will.

1. Find out what motivates you (you may think what you want from life and how being an IITian will make it easier for you to achieve it).You must have a reason why do you want to get into an IIT.Once you are motivated, determination will follow.But from here the real challenge starts, being determined is easy but remaining determined for 2 years will be tough job.
2. You need to be calm, composed & well prepared for any type of difficulty, ups and downs which you will face within the next two years of your study. You need to understand that failure is a part of learning and develop an attitude of learning from your mistakes. That’s how you will grow and improve.
3. Remember that only wishful thinking with no efforts will lead you no where.
4. A correct timetable is very crucial. Your activities should be planned. The time distribution for studying all of Physics,Chemistry and Mathematics in one day should be clear to you from the moment you wake up. Always aim to set constructive goals.
5. You have to always be sworn by three planning tools, a proper time table for each subject, long term and short term plans and a balanced study schedule which leaves adequate time for other activities.
6. If your parents could afford it, you should join a coaching institute, such that you get at least 6 hours to prepare for yourself.
7. Make a plan. Set yourself some deadlines for each topic and try to get them done. Also, it's up to you how long you study. It doesn't really matter how long you study, what matters is what and how much you study.
8. DO NOT MUG UP PROBLEM PATTERNS - that's going to really mess up your mind to a level where you would find it too hard to come back from - you probably won't be left with enough time to understand the topic later.
9. Do not jump from one to another book in order to search for new problems in the same chapter. Do one book thoroughly.
10. Follow the right(not many) books. Keep the sources minimal but be thorough with whatever you have chosen. Books like SL Loney, Cengage, I.A Maronfor maths, HC Verma for physics, NCERT, JD Lee, Morrison boyd for chemistry.
11. It is always better to solve less number of quality problems all by yourself than solving a large number of substandard and similar problems by yourself.
12. Don’t miss out lectures even when you know the chapter.
13. Time management and how you study that’s all up to you.

Thanking you....
