USA

Hi,
For under graduation, you need to write SAT/ ACT or AP along with TOEFL/IELTS as this gives better chances of scholarships and financial aid. Some universities may also require personal essay or SOP.

To pursue MS or MCA in any of the countries mentioned, you have to pursue B.Tech or a degree. You also have to crack GRE to study in USA and some universities of Australia and Canada. You have to appear for IELTS or TOEFL. The minimum score in GRE is 300 and in IELTS is 6.5 or 80 in TOEFL to get admission in a decent university.

Hi Ayush,
Both the universities are among world's best universities. For engineering MIT is unbeatable but getting admissions is not easy and unless you have an outstanding profile admissions and also financial aid is difficult. Please check the university websites for admission requirements and prepare accordingly.

The current situation in USA is not that good. Even regaining the money you kept for your studies in US is hard now. So, if you have good academics in India it's better to go to Germany where the education is totally free and all you need is to fund your living expenses around 7 LPA.
Even though you want to move to USA I will suggest something for you. It's not the scholarships but it's all about the instate tuition which is very less compared to any other universities in US. Apply to universities in Texas and get at least 1000 $ scholarship and you are eligible for instate tuition fee.

Hi,
As the situation in USA is worse and there are many visa issues in UK and you deal with commerce, so it is best for you to move to Canada or Australia. If you get into a good university it will be much easy to get PR in Canada and Australia. Even NZ comes into the same scenario.

You can keep them ready or ask your referees to keep the LORs ready but it won't be too helpful as LOR format is likely to change with every season. And, the university will send them the LOR format during the period of your application. You can always keep the draft ready and edit it later. At least, you can save pretty good time later.

Hi,
You need not worry about converting your grades. The university you are applying to will take care of it. They are aware of education systems worldwide. You may mention your percentage issued by your school and the GPA conversion will be processed by the US university itself.

It is not quite the same. Most of the core courses are same all-over. The electives vary. Universities in US have more options and flexibility and more innovative programs. Also, the way the programs are delivered varies.
