“Twelve semester hours of mathematics (MA) AND natural sciences (N) area courses, to include two hours of laboratory. Mathematics must be at the MATH 125 Calculus I level or higher.”
My ds is currently a CS major at Alabama and came in with 55 hours of AP credit, so I will try to help.
The AND means you need 12 hours of mathematics and 12 hours of science credits. Semester hours and credits are the same thing, so 3 semester hours=3 credits. So taking the Calculus BC exam and scoring a 3 or above will give you credit for MA 125 and 126 for a total of 8 credits for math.
For science you need 12 credits, with 8 of those credits being in a sequence. You can take Chemistry, and if you get a 3 or a 4 you get 4 credits, but a 5 would give you 8 credits and count as your sequence. If you take Biology and get a 3, that would give you 3 credits, but a score of 4 or 5 gives you 8 credits which would count as your science sequence.
Each physics exams gives you 4 credits if you score a 3 or above, but only choose one type of exam (either the algebra based Physics 1 and 2 OR calculus based Physics C exams). They will not give you credit for the algebra based exams and the calculus based exams (at least they did not for my ds). So if you can take both the physics C exams and do well, that would give you a science sequence.
If you think you could a least get a 4 on the Chemistry and Biology exams that would give you 12 credits with a sequence in Biology and you would be done with your science credits.
Like others have said, earning at least a 4 on the English Literature OR English Language exam would give you credit for EN 101 and EN 102 (required courses) and worth 6 credits. If you can take this and do well, it is a big help!
General education requirements also require 9 credits taken from humanities (HU), literature(LIT), OR fine arts (FA). Another 9 credits are required from history (HI) OR social/behavioral sciences (SB). You must also have a sequence of 6 credits in ONE of the categories: either HU/LIT/FA OR HI/SA. Ds took the AP Latin exam and scored a 4, so he received 9 credits which means he got all of the credist out of the way for the HU/LIT/FA category and his sequence is done. Now he just has 9 credits HI/SB to complete.
So, take a look at the languages and see if there is anything you can do well on.
Scoring a 3 or more on the psychology exam would give you 3 SB credits, and Human Geography would also give you 3 SB credits if you score a 3. Scoring a 4 on World History or US History would give you 6 HI credits each.
I will post a link the CS flowchart in case you have not seen it yet:
