“The expectations of life depend upon diligence. The mechanic that would perfect his work should sharpen his tools first.”
Let us assume that you, the average IIT JEE aspirant, are the struggling mechanic in the proverb. With the tools of your craft rusty, can you expect to get anywhere close to your dream? And yes you guessed it right. The tool here of course refers to your mind. With a brain that lacks agility one cannot aim at a goal as high as an IIT education. One needs to exercise his/her mind enough to face the tricks and intricacies that characterize the questions of IIT JEE.
The question is ‘What can be done to have enough blood pumped to those brain cells’?
The answer is to use the best IIT question banks to practice enough questions. However refrain from even touching those fancy looking IIT question banks before you are done with understanding the conceptual and theoretical part of a particular topic.

• Follow a pre-planned pattern of studies, and structure this pattern according to your study habits as well as strengths and weaknesses. In the planning phase just concentrate on getting your hands on the right books and IIT question banks in addition to planning the course of action.

• There are numerous Physics lovers who sit with the Physics IIT question banks for hours, ignoring the existence of the other two subjects, and vice versa.

Concentrating on your strengths is a good thing, but one must always remember to draw a line. Don’t overdo anything. Now it is understandable to have one’s own favorites when it comes to subjects, but don’t forget that you need to clear the cut-off for all the three subjects, and scoring 100% in one and 10% in the rest won’t do the trick.

• Always try to stick to your schedule. (Planning a schedule is easy, but following it is the hard part.) Now there would always be unavoidable circumstances, so remember while planning to make room for such contingencies. One must remember to always keep a margin for the possibility of time getting wasted.

• Once you have your plan in place, your study books and IIT question banks in place, you can start with the actual studying part.

• Remember to get proper recommendations about IIT books, study material and IIT question banks, because there are so many in the market that it would be very difficult to choose good ones without credibility check.

• Remember not to store stockpiles of books and IIT question banks. Just keep a few and practice enough.
There are many students who buy a hundred IIT question banks imitating what others are doing, but practice not even 10 questions while preparing. It can be overwhelming to see a lot of books and IIT question banks, so give your nerves some relief. By buying so many books and IIT question banks, you are doing nothing but giving scares to your own mind.

• The pattern of studies must always remain the old school one:
Concepts from basic books and online video lectures→ Questions at the back of your book → Solved examples from books a little higher level → Practice from IIT question banks → more practice from some more IIT question banks (remember practice makes perfect).
So follow the right approach, get the right books and IIT JEE question banks, and be ready to work hard (nobody drowns in their own sweat right), and you are all set for the preparation.
