TOEFL

From which college did you complete your PG?

Dear Shashank,
Easy or tough will depend on your own competency. Suggestion from me would be that you should check the formats and test pattern. Many people will be having their own opinion about it so it's up to you to judge.

Hi
GMAT requires 18 years of age and a graduation degree to be eligible. So, you can take GMAT and apply to Australia with that score.

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 Aryan,
Scholarships are on merit. They may offer you scholarship on basis of TOEFL or IELTS scores but these scores won't be the only criteria. You must have very good scores in your academics and overall a very strong profile.

Dear,
The SAT score eligibility varies from university to university. An ideal new SAT score in my view is 1200+ (higher the score, better it is) and with this score, you may target good universities in the US. As for TOEFL, it is more of an English assessment test rather than a competitive test. An ideal score for a UG course would be 80+ in TOEFL with no individual band less than 20. I'm not sure what you meant by "direct admission" and therefore cannot comment on the same.
Hope this helps.

Dear,
You need to sit for IELTS/TOEFL as well apart from appearing for SAT. The SAT subject test is required or recommended by a select few universities. Therefore, it makes sense to email the university and confirm with them about the entry requirements. However, say for e.g, if you are strong in maths subject, it always makes sense to highlight that by taking the maths subject test. This way a few of your weak points might get ignored by the admissions committee.
I hope this helps.
