When he gets to an unknown place, a young student, must find out where he is.

I am a big fan of succinct loglines, however, yours might have taken it a bit too far, I can't really visualize an unknown place or an unknown person. (The last from you quick synopsis)

"When he wakes in a magical land beside a beautiful girl, a gifted math prodigy must use all his skills to determine where he is and how to get back to his own world."

Obviously, yours will be different. Was the lead transported to a different world? Is it a different city? Is it a basement with two people in handcuffs and one must chop off their hand to escape? I can't tell from your logline.
