Ques. Did you take coaching classes? Mention their role in your Story (At least 70 words)      

Ans. Yes, I took coaching classes for short term (45 days) from ACE Hyderabad. It played a very major role in my GATE score. The short term coaching was very intensive. It was from 6.30AM to 8.30PM for 45 days excluding Sundays. It looks very difficult to sit for such long hours. But the lecturers were very highly talented and you feel beauty of the subjects. You feel very interested towards the subject. Generally in local B.Tech colleges, you don’t get much knowledge through all your lecturers. So, you feel very disinterest in those subjects. But once you attend such coaching classes, you will find very motivated. It played a very major role.

Ques. Share your Strategy and how did you overcome the weak areas, what special efforts did you put in?

Ans. I started thinking about GATE from the third year of my UG. Back then it could be attempted in the pre-final year also. I decided to appear for it in my third year.

I started preparing from December (exam was in Feb). I tried to corner out 5-6 most important subjects and made sure that I cover each and every portion in those. I used to spend my time effectively in trying to juggle between aptitude and maths too. This portion in the GATE paper is very important as it accounts to 30% marks. I had covered 60% of the portions by Jan end.

In the first attempt I did well. I wanted to give a bigger short in the next year. I started preparing more diligently. I took up a lot of mock tests and analyzed my strength and weaknesses. The more and more you practice, confidence develops in you and you will be able to attempt more questions. Do not put doubt full answers as it will have negative marking. The marks you obtained by correct answers will be lost with the wrong answers. So avoid this.

At the least try to hit minimum 50/100 score in your mock tests. This builds up your confidence very much. I tried this during my mock test and resulted positive in GATE 2010.

Try maintaining time while writing mock tests at home. Don’t get distracted. Spend complete time allocated to the test at a stretch. Check the subjects with more weightage in previous papers and build up your strength in those subjects. Take advantage from aptitude and reasoning questions. ALL THE BEST
