UC additional comments section?

<p>Okay so I finished plugging in my grades for the UC app and had one final question. I took a summer class a couple of years ago and I ended up getting some unsatisfactory grades and it really brought down my gpa. However, at the time, I was working to cover the $800 tuition because my family couldn't afford it. Trying to get the money together and study at the same time was a big pain, especially when the class crammed a whole year of math into 3-4 weeks.</p>

<p>Is this worth mentioning in the UC section and Common app additional comments? I feel like i'm making an excuse for my lack of motivation and effort. I did end up getting 2 B's, which might not sound that bad, but it hurts my already low GPA.</p>

<p>Bump. ^_^</p>
