Here is the sentence:

At the beginning of class, Matt realized that he had forgotten the essay he had wrote at 4 a.m., so he smeared blood-like streaks of red pen at the corners of his mouth and told his instructor, Dr. Borglum, that muggers had beaten him up before stealing his backpack.

The second verb, had wrote, is incorrect. As you know, this verb requires the past participle written because of the auxiliary verb had.

Write is an irregular verb; the chart below shows its forms.
