Fastest second AA you can get if you already have a first AA ?

[nyvrem]

I have a first general AA (i think the AA just says AA in general studies), and I wanna get a 2nd AA in Computer Science, where's the cheapest option available ?

I was looking at TESU and don't look worth getting just an AA in CS. Would be sorta worth it to get an AA in CS if i was completing a BA/BS in something else during the same period.

but for now, just wondering what's the cheapest option to get an AA in CS if I already have a first AA.
