I keep getting 40% on every test I take

No matter what the issue is, keep in mind:

  1. What you are doing isn’t working
  2. You want to succeed
  3. Your college wants you to succeed
  4. Your college provides resources (that tuition pays for) to help you succeed
  5. You don’t want to look back and not have done everything you could

Now you might feel weird/strange/scared/apprehensive about asking for help.
Do it anyway.
If you have trouble doing getting help from tutors/professors/counseling center/study skills center then ask someone, anyone you trust to go with you.
