I wish to apply for M.Sc studies in Computer Science to 3-4 universities. Only one of them requires the applicants to take a GRE (general test), and my question is as follows: is it a good idea to send the scores to the rest of the universities even though they do not specifically require it? Will it affect my chances?
FYI: I did one practice test and didn't get a good Quantitative Score (only 145), although I took the test without preparation, without paper (soon after taking the practice test I've read that is allowed scraps of paper) and after 4-5 years after finishing undergraduate studies. I think with 2 months or so of moderate studies I can get about 160. What do you think I should do?
