second visa character check

I have a minor conviction/ fine for possession but didnt knew i had to declare it

Oke i got a minor conviction/fine for possession of xtc. The first offence ive ever had. I didnt knew i had to declare a fine so do u think there might be a problem at the border or stop me?

FOR GOODNESS SAKE-- we went over this whole thing a month ago! Go back and read what was written then. And move on.

The main thing is, i asked it at the police office and its recorded however minor as a conviction!
I didnt knew it before so i ticket no at my 2nd application.. i leave in a week so i donit know what i should do.m usually they donit refuse people for this offences so i want to tick yes or leave the box blank but im scared that they will say that i lied on my application...
Thats the point..

You've been given advise. take it or not, going on about it continuously isnt going to change things. With this nervous behaviour, you should now expect the worst on arrival.
