May and June

Deposit deadline – Typically, colleges will have a deposit deadline of May 1. You may have already signaled your intent to enroll, but now it's time to commit financially. Your acceptance letter should include all the details.

Final transcripts – Once you've graduated, send your final high school transcript to your new college. This may help you secure a scholarship or qualify for other competitive academic programs.

AP exams – If you've been taking AP classes in high school, you'll be taking your national exams at the end of the school year. This is a huge opportunity that you shouldn't let go to waste. A high score or 4 or 5 on your AP exam will translate to college credit. Some students begin college with much of their freshman requirements fulfilled through AP credits.

Thank you letters – You didn't get here by yourself. Chances are there were many people who helped with your college applications. Take the time to write personalized thank you letters, especially to school counselors and teachers who wrote letters of recommendation. They will appreciate the gratitude and will be happy to know where you enrolled.
