Before going to exam keep your mind fresh , sleep well the before night get up have a fresh bath , eat some idlis it is the best tiffin before exam, once bow your head before god and pray for a few seconds . After taking the paper , read the entire question paper once by spending 10 minutes . Don't think its a time waste , it will give you an idea of how the question paper and its level .
Now start answering the question paper , you have 30 1 mark questions and 35 2 marks questions right. First start with 1 mark questions and answer those questions which you can do it by just seeing at them without much effort . Now go to 2 marks questions , in a similar manner answer those questions which you can answer without much effort . ( One thing keep in mind if you are spending some time on any question spend some more time on it and solve it ) . Now once again come back to 1 mark questions and try to answer those questions which you think you can solve it or you get some idea , if you don't get idea leave it and move to next question . After the completion of 1 mark questions once again go to the 2 mark questions and try to answer them if you get an idea and think that you can solve them otherwise don't waste time on it and move to next one . ( As you have already read the problems meanwhile your mind will be busy in thinking about that problem and if you gets a solution go back and answer that one ) . In this way try to do in a iterative manner using a greedy strategy.
Why i follow this strategy ? If you go on answering the questions in a sequential manner may be i could finish only 60 questions and there are a bunch of easy questions say 10 to 15 easy questions from 50 to 65 then i would be missing them . even if you solve a hard problem you wont be getting extra credit for that . That's why i say do it in a greedy manner .
During following the above strategy , please make a mark against each question whether you have answered it or not , so it will help you while retracing the path .
*** Another important thing is marking the bubbles on the answer sheet please see the question no correctly and mark against it , if you loose the continuity some how then your entire effort will be in vain and it will affect the remaining questions also . so , be cautious regarding it .
Another important note while answering is , the guys you might be experts in answering the EAMCET papers so you might be knowing the well known theory " elimination , substitution etc .. of options " and sometimes you are given some big problems to solve which may take long time to solve like construction of parse table entries , the intention of the examiner is not that you do the entire procedure . If you know the properties of the answer then you can answer them very easily . So make a note of this .
One of my suggestions is first answer those questions which belong to those categories you think you are confident and feel you are very good say (Databases , Algorithms , Data structures )
These are just suggestions . All the best to all students writing GATE 2010 hope you will come up with flying colors.
