shouldn't do that in the 1st place, even if you did, you should be smart enough to take advantage of it and learn from it not buta-buta submit it to your lecturers / tutors not knowing what did you submit.

Now regarding what suits you best, i've no idea, you didn't provide detail of what you are capable of, your strong points nor your weaknesses.

Since you are fresh and when you are applying for a position which require no experiences, you dont have to worry about not knowing anything, they are aware of freshies dumbfounded, this applies to me as well when i was a fresh graduates.

What they are looking for is confidence and willingness, just remember, this is not the university, copying work from other may get you into trouble big time.

Find a book about how to communicate effectively, read it and learn from it. That'll help you in conveying your message effectively in an efficient manner.

Start focusing on your strong points rather than your weaknesses. That should really hit the spot.

All i have say is, you were smart enough to enjoy your sophmore days by letting others to do the work while you copy them but you are stupid enough not to gain advantage of that situations and make it a shorter learning process.
