Hi Viren Singh,
You don't have to take GRE and SAT at the same time because SAT is for UG course and GRE is for PG programs, these tests are mainly for USA. So, first you decide what to study and then appear for the exam.

Hi Spandan,
Somaiya would be better due to its brand name and location. The average package offered is around Rs 9L, and is one of the top B-schools in/around Mumbai. The new IIMs are not great in terms of placements and ROI; it will take some years for them to be established. Still if brand name matters to you than placements/ROI, then you can go for them(specially Amritsar & Nagpur). Good luck!

TIME institution is the best. IMS is the best alternative. Don't choose any other centres which are emerging as they don't have successful track records.

For Diploma in ME, you need to get more than 60% in class 12th. Particularly, you need to score more than 60% in science and mathematics to get admission in any decent college.
Best of luck.

You have chances to get admission in new IIMs (Sambalpur, Bodhgaya, Sirmaur and Srinagar). You have chances to get calls from IIM-Rohtak, IIM-Udaipur, IIM-Kashipur and IIM-Trichy.

You are advised to evaluate BITS Pilani, WILP M.Tech Software Systems for further studies by distance learning. It has good brand value and acceptance in IT industry.
