@rescinded Is your admissions officer Quincy Jones? That guy NEVER gets back to anyone in a timely manner. That alone is grounds to complain. You really need to be firm. Literally - send a letter to the dean. I’ve heard it works. I think everything in your story should be included. Someone said to leave stuff out. I think all of it is relevant. Number one, whoever told you you cannot appeal, I’ve never heard of such a thing. Based on the fact that your advisor did not respond in a timely manner meant you did not have the opportunity to SIR UCLA.
I think you have an extremely strong case. For God’s sake, where the humanity?
BTW, if he is Quincy jones, google his name in the UC transfer forum. His name is all over the place in terms of not responding. Include copies of them in your documentation.
