Conversation class is 100/500.
61/100 is ample.
If you had worked hard this semester you would have easily scored enough points in your academic class to have passed E3.
You did not work hard, so you failed.
Do not try and beg and plead and shift the blame to someone else. Take responsibility for your own inadequacy, laziness and academic frailties. Adopt a little introspection and assess what you need to do better, but please desist with this undignified display of subservience.
All the best
