From what you have written, I can't see why they said that you made no sense.
Your punctuation, however, does need some work- you're putting spaces before commas- just put a space after a comma, not before.
You''re also using a comma (,) instead of a full-stop (.):
This should beI loved it , Actually I wasn't studying it
I loved it. Actually I wasn't studying it
