Hi Pooja, GRE is not required for admissions in any German university. However, good GRE scores can increase your admission chances. If you are planning to take the GRE a score above 310 would be good.

Dear Shaik, GMAT is preferred, but if you may find it tough you can consider taking the GRE. IELTS or TOEFL are English proficiency tests,you can give either one. Foreign MBA also requires applicants to have work experience, without which you will not be accepted unless you have an outstanding profile. Visit some university websites and try to understand the eligibility requirements, this will help you prepare.
Best Wishes

GRE is the standardized test for entry into Masters program in USA, required in other countries too but vary with universities. Since it is a requirement you can infer the benefit, a good GRE score will help you compete with other applicants and might help you with a scholarship too.

A GRE score above 315 and a TOEFL of 100 or more will do you good. Most Ph.D programs in USA are fully funded, so you need to be accepted first. All the best.

Hi Vag,
You will be eligible to apply with a valid IELTS score. Good GRE score will definitely help. Admission decisions are taken by the university, so we cannot really say anything, but you have a good chance. Letters of reference and personal statement will be very important. Check for deadlines and apply on time.

Hi Abhishek,
If that is the GRE score, you can target some of the top universities. Your grades are good enough as well. You need to take the IELTS or TOEFL too.
