Hey, i am planning to give my GRE in April first week, and toefl in April last week, i am planning to pursue MS in computer science in US, i tried googling for which session would be most appropriate for me to apply, but couldn’t find any specific info on this.
Please advice on this, and please let me know any good university in US for MS, i am aiming for a GRE score of ~320. 
There are many “good universities in US for MS.” You’re the only person to tell if any of them is good for you.
GRE is just a part of admission. You also need good GPA, good letters of recommendation, and preferably some research experience.
Application to grad school is typically done during November - December the year before (e.g. Nov. - Dec. 2014 for admission in Fall 2015). If you plan to take the exams in April 2015, it’s too late for 2015. There are schools taking applications for Spring, but the number of these schools is very small.
