Mistake in Extracurricular Activity

<p>I sent my UC application a while ago</p>

<p>and I put that I was in MESA, an engineering program</p>

<p>just today I found out that I wasn't officially in MESA because I missed some deadline I did not know about so I won't be able to compete with other schools</p>

<p>I've been to several meetings and I was completely unaware until now</p>

<p>will this be bad in my college application?
if I get into the UC I wanted, will this ruin it because they would think its a lie?</p>

<p>I heard that 10% of people apps get checked and if the find something wrong u get an audit</p>

<p>its the only mistake I've made in it</p>

<p>will this ruin me????? I asked my MESA teacher what to do and he has no idea</p>
