<p>There are a lot of parts to getting in to college – one of which is taking the time to fill out the app and meet the deadlines. There are a lot of people here on CC who moan about missing deadlines and is it still possible to get into their choice school. The OP obviously worked hard to get into college, but I don’t think that mom imposing rules with consequences that OP had control over (finish the app, then go to concerts) is not out of line at all. I also am fine with mom taking some credit for OP “getting into college” since she helped him with time management.</p>
<p>It would help OP to realize that a lot of people probably helped him get into college – teachers, counselors, parents, etc. – and be grateful for their help.</p>
