AAT Boost for Transfer

I heard that getting an AAT will boost your gpa .1 and since I have 2 does that mean itll boost my gpa .2? I also heard that it gives you a guarantee admission to 1 CSU, can someone explain that pls. Also any information on AAT will be helpful!! Thank you (:

See link which explains the AAT or AST. You get priority and some campuses will give you a GPA boost.

If you are not accepted into your choice campus, then your application will be redirected to another campus that had space.
