Not sure what to think about not entering my failed UUU grades

I went to Uni in 2009 at 19 ( I failed my AS levels, UUU, when I was mentally ill during that time) - therefore I did BTEC for 2 years. I can't remember if I put these UUU grades on the application but I don't think I did on the advise of my teacher.

I applied for 2013 entry but ended up not going. I didn't put these UUU grades. I got offers but long story short, I didn't go. I've done the same for 2014 entry without the UUU.

I've been reading up on declaring grades and failed ones and it's not absolutely clear but I seem to get the impression that I'm meant to put the UUU grades on the application? I DO have the UUU certificates. And I'm quite worried actually having read up on this through tsr, and how you can be caught at any time. I'm not quite sure what to do. I applied 3 days ago.

Should I ring up UCAS and ask them to add this or leave it? I'm really not sure what I should be doing but I don't want to put myself in danger. What's the worst that can happen? I'm actually kind of scared :0

You are safe if you don't put U's down.

My college and secondary school both said the same.

Getting EEE is worse than UUU !

The reason you don't put U's is they are not certificated.

Grades only need to be declared on UCAS if they are an E or above, so you do not have to mention any U grades on your application.
