I'd suggest looking back at the problems you got wrong and see if there are any connections. Maybe there are particular types of questions you are consistently getting wrong; mark these down as your weaknesses. Go back to your study material and review the process for solving these types of questions. Are there key points you're missing? Are you making simple mistakes? Reevaluate how to approach these and maybe you'll start to see some improvement.

Any new study groups
