DrAtkins : You are correct, people (like myself, before) got straight into 4 year universities right from high school. When I started college before at the 4 year, I had taken so much math that I was able to go directly into calculus, and was able to go directly into general biology and general chemistry as a first semester freshmen.
However, 4-5 years had elapsed since I went back to school, and I was placed in classes lower than where I started the first time around as I had forgotten a lot of what I used to know, which is why it has/will take me so long to complete my courses before I can transfer.
Taken from the assist transfer website, classes I need to transfer as a psych major to UC
1. Biological sciences, 2 courses (listed are general bio 1, human physiology, and intro to physical anthropology. For general bio, prereqs are intro chem and general chem 1, for human physiology, prereqs are gen chem 1)
2. Quanitative: 2 courses (listed are intro stats, calculus 1, calculus 2, linear algebra, discrete mathematics)
I have to take intro chem and gen chem (2 semesters) in order to take a prereq to transfer (3rd semester)
I need to take trig, precalc, and calc 1 (3 semesters) in order to to transfer, despite the fact that I took trig and precalc back in HS, I tested lower when I started school again.
If I want to transfer as a bio major, classes needed:
-Biology: (gen bio 1 and 2, requiring 2 semester of chem before I can start the sequence) = 4 semesters
-Chemistry (gen chem 1 and 2, organic chem 1 and 2, requiring 1 semester of intro chem before I can start the sequence) = 5 semesters
-Math (2 courses needed: select from calculus 1, calculus 2, discrete mathematics, linear algebra and differential equations, need trig and precalc before I can start)= 4 semesters
-Physics (not required, but 1 yr of calculus-based physics strongly recommended prior to transferring to increase chances basically) Can’t start sequence until after taking calculus
My understanding is that you can’t transfer to a UC as an undeclared major, and you are unable to change your major after transferring.
