I took a MATH class (Trigonometry)a few semesters ago that was only for CSU credit so, I couldn’t add it to my application under “list of classes.”
What I’m worried about is that when I get accepted and have to submit my transcripts, the class will be on there and, will they decline my offer since I wasn’t honest on my application?
As far as I recall, trig in general is not UC transferable, and that’s probably why it was not showing up on your application. If you are still in doubt, call UC and ask. Most of the time they are very pleasant and helpful.
