I omitted past colleges attended in my application, got accepted, and have been taking classes

First off, yes. I know I did something wrong. I was just getting out of the Army because of my severe TBI and was in a really dark place. So I decided to not mention the community school I went to after high school. All of which I failed by not going to because I was a dumb 19 year old kid and a few random online classes here and there that I believe I failed as well? I honestly can’t remember. I am doing well in school now with a solid 3.0. My question is this. Should I come clean and tell the college i didnt put those in or just let it be and hope I don’t get caught. I need actual answers here please not obvious stuff like “you shouldn’t have done that”. Thanks

EDIT:

Or would it work to play dumb and blame it on my TBI and say I was looking at my records and saw I must have forgot to include it?

I don’t think they are looking into your past at this point. So it’s an ethical dilemma not a practical one. You must decide for yourself.

you need to come clean.

WILL show your past enrollments, so in this case, honesty is the best policy.

I’d come clean. You will always feel guilty if you don’t.

MODERATOR’S NOTE:

Closing thread. OP stated at the outset that he know’s it’s wrong. Whether the dilemma is ethical/practical is of no import to this thread, because this site will advise the right thing to do (as the 2 posters above have suggested), but our purpose is not to assist users in skirting issues.
