CSU Application Help?

<p>My friend transferred mid year in his junior year from one school to another. The problem was that his old school was a trimester school while our school is semester. He's trying to apply to csu but it's saying he's behind on credits because he only officially completed 1 trimester and 1 semester. He did stay for the first half of the second semester but left before the final grades came out.
How can he input this in or is he stuck missing out on the 3 credits?</p>
