Contact your admissions counselor and tell them you are ready to accept your offer. This will reserve your spot in the incoming class.
You can also make the $200 deposit, allowing you to proceed with the registration process. The deposit is not an extra fee. It is credited toward your student billing account for next semester. You can complete your deposit by logging into your TMU account. If you plan to live on-campus, you will also pre-pay a $300 housing deposit in April.
