more tips....

The best that i've realized and found in this exam prep is, you cannot move a mountain in a day. A consistent and steady method is the only way to do it.

• Never over do yourself even if you feel interested in a particular day. Moderation and consistency are the two main ingredients to success. 3 hrs a day for 3 months is the most effective way to prepare. If you work then 2 hours a day for 6 months is good. (i over do sometimes and dont do the next couple of days, then i try moderation and steady speed, it works...try and let me know)
• Plan your time and stick to the schedule. This is not a matter of discipline but a matter of behavioral technique. conditioning as we say. your brain gets ready to assimilate the study experience and stuff you are taking into the brain in some fascinating fashion and yield you result. 
• Always study in multiple ways. not only by reading, switch to videos when u r  bored to read, switch to audio when u take a quiet walk, write concepts down as puzzle for yourself to recollect and see how much your brain can recollect concepts. sometimes read extensively and repeatedly. this is a principle of recency. the brain easily remembers things repeatedly exposed to. Do it as a game not a study routine. The more interested you make it the more the brain is going to be active to absorb it.
