Hi Garima, GRE has no such qualification requirement or eligibility. You take GRE to study MS in USA. To pass GRE you will need to practice a lot, take regular mock exams and work on your weak areas. Check the entry requirements on university websites first, every university has their GRE score preferences. Atleast 3-5 months will be required for GRE preparation.

After 12th, you need to take SAT in order to be eligible to apply to a lot of major universities abroad. However, it is not compulsory. Some colleges do not require SAT scores. Some require ACT. But some require none of them. I would suggest you take SAT preferably in 12th grade or even after that as soon as possible and then look into individual websites of the colleges you want to apply to. To check if they accept TOEFL or IELTS. Both of them are English tests. some colleges ask for TOEFL and some want IELTS scores. If you don't know how to get started, attend some study abroad fairs.

GRE is for PG or Masters level studies in USA. SAT is for undergraduate. First learn about the differences and decide what you want to study.

Hi Gnanesh, if you want a good seat in top universities for you're future education it's not at all enough. Prepare well and crack it with higher scores for you're future.

Hi Urvil,
In GRE, the Verbal and Quantitative section score range is 130 -170 score and Analytical Writing section score is between 0 and 6. Try to keep your verbal and quant section score somewhere within 150-155 and analytical section score around 3.5 to get the average score. There is no passing score as such. Maintain the average. If you don't answer on any section it will be reported as No Score.

Dear Urvil!
It seems like you are comparing an Apple with the orange. (#) JEE is the core technical exam required for studying Engineering in India. Wheares GRE & TOEFL is for foreign study (Bachelor's). (#) In general, JEE is quite more difficult because of the syllabus content and the complexity level. So prepare accordingly. Hope this helps. Good Luck.

Firsrly, its important to have a clear structure for your study hours. If you think that you'll only be able to concentrate on a single section for an hour or two, then adjust your study plan accordingly by factoring in a break, or a change in your area of focus. Using practice tests is a tried and tested way of tracking your progress, and a handy way of highlighting any weaknesses in your strategy that you might not be aware of.

IIM prefers GMAT for executive MBA but some of them like IIM Bangalore also prefers GRE. So, you must opt for GMAT if you are not targeting any particular IIM which also considers GRE.
