Request for correction of a subject on my O Level Verification letter

Response to this request is long overdue. By law, under all circumstances, Uganda National Examination Board (UNEB) should have responded by now (details). You can complain by requesting an internal review.

Dear Uganda National Examination Board (UNEB),
I am Isabirye Emmanuel of index no. U0018/314 who sat in the year 1983. I am requesting you change one subject on my O Level verification letter. The correct subject is Commerce instead of Geometrical & Building Drawing.
Hoping for your usual positive response.
Thanks

Yours faithfully,

Isabirye Emmanuel
