Gre score card

I got 294 in Gre in first attempt and 305 in 2nd attempt.What should I do if the visa interviewer asks me why I scored less in first attempt after looking at my gre score card?

Well, you are the one who took the test, you better know the answer. Honestly, you should not try to fabricate answers or get inputs from forums like ours for saying fabricated answers. Be confident and state the truth, you will be fine.
