Have you submitted it to your teacher?
Iereiy's second sentence says "In fact I had submitted this a week before". I took that to mean "I submitted this a week ago". As long as it's been submitted, it doesn't really matter if the OP has had it back with the teacher's comments yet.
I consider it a comma splice because they are two independent clauses, but I am not a teacher.Everyone is required to complete at least 10 years of studies, it differs between countries.
