GATE

Dear
Yes it is totally possible and SELF STUDY is the only MANTRA for success in GATE.Coachings can just teach you and provide you with material but its you who need to study. The coaching material is easily available in market now days. All you need to do is just follow some simple path.
1) Get the syllabus of your trade and collect the previous year pattern of your paper and from there identify the subjects which comprises of maximum marks in paper every year.
2) Start with the subject that comprises of MAXIMUM marks to the subject with Least marks.
Usually it has been noticed that in every branch there are 4-5 subjects which comprises of 45-50 marks totally. So you should target those subjects firstly and once you are done with these subjects switch on to APTITUDE AND ENGG. MATHEMATICS .
3) Revise every subject at least once in a week because if you do not revise the subjects frequently you would soon forget the subjects.
4)Make a separate notebook for formulas and just revise through that because the most important part of gate are formulas. Some questions are easily solvable but students forget the formula because of which they those marks even in easiest question.
5) Join a good test series. May be ACE ACADEMY OR MADE EASY TEST SERIES( Ace test series is more relevant to gate pattern but actual competition is reflected in MADE EASY tests)
6) In last 30 days just solve previous year question papers, give tests daily(FULL syllabus) and revise formulas.
