How to study ?
I will tell you three golden words . Read the subject by posing questions " What " , " How " and " Why " ( In telugu we say " enduku " , " emiti " , " ela " ) . And another word is always stress to analyze the things by working out on the paper and don't take anything for granted , then things would be fine for you and life will be smooth . I promise you that these words are very powerful .
* I tell you these Brilliant tutorial materials and all will not help you . follow standard textbooks , read the concepts , understand them , think about how they would be useful and can be applied practically ( what , how , why ) . Try to work out the exercise problems given at the back of each chapter in the textbook ( once again not all , only those which you feel like useful for your preparation , there is no point in wasting your time over 3 starred problems ) . Read two different subjects in parallel so that you wont feel bored . Try to answer the questions related to a subject after you finish studying it from both " Multiple choice questions " book by williams and questions from all the previous papers related to that subject . This would give you some insight on the GATE questions and build your confidence as well .
** Another thing is that don't worry whether i can do well in GATE as my percentage in university exams is very less , for people who think like that let me clarify your university percentage has nothing to do with GATE both of them are entirely different ball games all together . The student with good basics , understanding , application will definitely succeed irrespective of the percentage . one more thing is , don't worry even if it was too late to start the preparation for one reason or the other , i tell you 2 months is more than enough for the preparation of the CS paper even if you have not studied much for your university exams .
*** One important note to the undergraduates , see you believe it or not these 4 years of your B.Tech are the best days of your entire life so enjoy them to the fullest , bunking the classes and going to movies , roaming with friends , going to second show movies , playing cricket , getting ragged by the seniors and ragging your juniors etc ... . Studies is only part of life , it is not everything in life , there are many more beautiful things in life so , don't miss them ( you cannot reuse time unlike space right )
