Dear Partap, you can give GRE, alongside you must give IELTS or TOEFL too. Check with the universities if they will accept three years bachelor degree as most universities in USA require a four years bachelor degree. Scholarships are awarded to meritorious students by the universities.I will advice you to first research on the universities.
Best Wishes

Shortlist the universities in which you are interested in and check the minimum requirements. Most of the universities require an overall minimum of 6.5 with no band less than 6. Still you can manage to get conditional admit with 5.5 score in few universities. But, it might create some problem during VISA.
I would suggest you to retake IELTS and apply later to the universities

Dear,
You may try universities that accept medium of instruction letter in case you don't have the requisite IELTS score. However, you would have to consider a tuition fee budget of Rs.30 lakhs. Hope this helps!

Requirements vary from university to university. On the whole 6.5 or 7 is required. You may refer to German Academic Exchange Service website for more information.
Best Wishes.

you can get admission in most of the European countries which accept IELTS 5 band score like Poland, Czech republic , Spain , Italy etc. apart from this you can also apply to USA with ESL pathway programs which certain universities offer. These programs are design in such a way that you need to study English for a semester and then you can normally progress in your Bachelors program.

General requirement for ms is 6.5 or above in IELTS + your bachelor's marks and GMAT/GRE score.
