"This year's math and physics classes..." - grammar

Is this sentence correct?

This year's math and physics classes were the detonators, but the process of me applying to the MIT began many years ago.

thank you for your help

Good morning.

This year's math and physics classes were the detonators, but the process (Do you mean the actual application process, or the desire to attend this institution? If the latter, you should change "process" to "fire": "...but the fire for me to attend MIT was lit many years ago.") of me applying to MIT began many years ago.
