Dear Gugan, I want to reiterate that you are not what people want you to be and you shouldn't even think about that. If you have the caliber of preparing on our own and have the confidence, you might as well surprise them. There are lakhs of students who take special coaching and don't even qualify for the exams unfortunately. With all due respect, yes coaching centres teach you  the short cuts and help you to train with exams and seats in mind. But if you prepare smart enough, you can pull it off as well. What we would suggest is to go through the syllabus once. Most questions are asked from NCERT. Cover NCERT from page to page and prepare religiously. Practise atleast one sample paper a week and keep checking your progress every week.

hello,

its not true that you cannot qualify in jee main with out coaching. the main thing is you need to get a high score to get admission in top engineering or other courses institute. now it depends on you how is your 10+2 course studies. and how much you can solve by your self. we need guide for exam to get solves the question and theory in low time. hope you may understand.
