i m getting all repeated questions in quant..is it that grockit have limited no. of qs

The majority of students don't run into repeat questions often. Students that create a lot of custom games with specific skill tags increase the likelihood for this to occur. We are continuously adding new questions into Grockit so repeat questions won't be an issue for anybody. We hope it has not been a significant problem for you. Thanks very much for the feedback.

The free accounts allows you to answer up to 30 questions, and paid a/c not limit for that. ok
