Well, The first step towards achieving an advanced degree from the American Universities and Institutes is to qualify the examinations such as GRE, GMAT, SAT etc. Every year more than 100,000 students come to United states to obtain degrees from top 600 universities. The GRE score required for admissions in each university is different, depends on the education policies, standards and ranking of that university. Therefore it is extreamly important to get a high score in GRE (above 1250) to get admission into a good University.
One of the most important factor in cracking GRE is to practice, practice and practice. So here I would like to give some information about on-line GRE practice tests, that will help you to practice online and get used to the tests.
