when i can apply for GMAT while doing job or after btech? is there universities which donot prefer job experience ?

You can apply for the GMAT anytime as and when you are ready. Do not make a hurry to give the test. Give yourself time, prepare hard and when you feel you can score 700+, you should start take the GMAT. Take as many mock tests as you can while preparing. It will help you boost your confidence.

Any time is right time to start off your GMAT preparation...but it is better to give with some experience as many universities prefer students with workexperience.Yes there are universities which give admissin to freshers as well.All the best:-) Please select the answer as best if you feel so.
