The correct answer is “It depends on the school”. In general, no, the 3 in French will not fulfill your language requirement. The college may have an internal placement exam which will allow you to place out if you score high enough. The freshman writing requirement may be waived as a transfer, not because of the 3.
Did they just skip you to English 2 or did they actually reduce the number of courses you need to take? Did you actually get credit for the 3 as a class?
In general, you need to check the AP acceptance of the universities you wish to transfer to. They will give transfer credit (or not) directly from the AP scores, not based on what your current college gives credit for. This applies to UCs as well – they give credit unit for scores of 3, but may give subject credit only for 4 or 5 (e.g. UCB allows AP English to count for first semester English composition with a 4 or 5, and most divisions allow AP English literature to count for first and second semester with a 5; score of 3 satisfies only the entry (remedial) level writing requirement).
However, for foreign language, you just need to take an advanced enough level college course to fulfill a foreign language requirement. For example, if the university requires a second semester college course but does not accept AP credit for it, you could, if your knowledge of French is good enough, go directly into a second or higher semester college French course without having to repeat the lower level(s) of French courses.
It probably depends. I was surprised talking to Temple admissions that they don’t transfer individual classes if you have an Associate’s - they said they “transfer degrees”. I have no idea how many schools have that policy, though.
Looks like you are in California, based on other posts. If so, if you transfer to a California public university that accepts the IGETC pattern (certified by your community college) as completion of lower division general education requirements including English composition, then that may be a way to satisfy that requirement without worrying about whether your AP score is high enough for your transfer target school. Check with your community college’s IGETC certification criteria and how your AP score may fit into it, as well as how the UCs you are interested in accept IGETC.
Of course, if you transfer to an out-of-state or private university, that is unlikely to apply. Your other threads indicate Michigan as a school of interest. Be sure to check its transfer credit database for courses at your community college, since Michigan has a reputation of being stingy with transfer credit, sometimes forcing transfer students (and frosh who took college courses in high school) to repeat a lot of what they already learned.
A word of caution regarding STEM transfers. This does not apply to all majors.
I did jog for some years with math teaching faculty in a STEM university. We talked a good deal about the research math faculty had done on an ongoing basis regarding AP scores of 3. They concluded that students with scores of three were, in general, having trouble with subsequent math courses so they raised the requirements to 4 or 5. The math sequencing is very pyramidal. One does not want problems to show up on the next instructional story. A student may not have the time to identify and patch the foundation. Not all of these requirements are simply based on the credit issue.
