I am pursuing 7th Semester B.E.(Mechanical Engg) under VTU at Tumkur, Karnataka. My overall CGPA(till 6th Semester) is 9.44 and at H.S. about 91%. I wish to pursue higher study M.S. at a good University in USA preferably for 2016 September intake. I am yet to take the tests of GRE and TOEFL. I am also contemplating to join a good coaching institute for GRE + TOEFL (+ Admission Counselling Services). Now I have the following enquires:
1. Is it already late for joining a coaching programme so that one is ready with the scores for applying to good US universities for 2016 September intake which award reasonable scholarships?

2. If yes, then is it reasonable to wait for February 2017 intake? In that case will it be possible to get good universities and reasonable scholarships?

3. Since the regular classes in my college are under full swing, I have to take up only weekend coaching. In which case, will the GRE classes and admission counseling process will occur simultaneously? If so, how will be the time adjusted? As my time to spend at the centre is fixed and cannot be extended by no means as I have to get back to my college.

4. Some students like me are not confident enough by themselves. We think we need guidelines from coaching centres. Which of these are good? What about Princeton review?
5. Do you think academic counseling services where they guide from selection of universities up to preparation of sop and essays up to getting of visa etc are essential for a novice? Do u think these can be managed with online help?
6. Is it that the most universities have their deadlines of applications with scholarship is 15th December of the previous year for September intake next year?
