If the two math are AB and BC, then they are unlikely to be difficult for a student on the +2 math track. Even BC without AB is unlikely to be difficult for such a student. Statistics is usually a relatively easy course.
Fos CS, CS principles is generally not difficult. CS A is mainly if the student is interested in major in CS or similar, so may not need to be taken.
So it is like that only the two science ones would be “hard” or high work for the student, which could leave capacity to take AP courses in other subjects.
AP English courses are typically honors options of the usual grade level English in 11th and 12th grades. Similar with AP history and government. AP foreign language is usually at a designated level (4, 5, or 6 depending on high school).
The kid was thinking of AP Physics 1 and AP Physics 2. Is that a good idea? Or need to replace Physics 2 with Physics C (again there are 2 options for C).
Actually, a more direct way is to ask the counselor what the UC ELC benchmark GPA is for the high school (which was determined from a recent previous class), then recalculate the students GPA for UC to compare with the benchmark.
Asking for the records release appears to be for determining the UC ELC benchmark GPA for future classes (see the linked page, box titled “How does UC calculate my school’s historic or benchmark GPA?”).
Physics 1 and 2 are non-calculus physics courses similar in content to physics for biology majors. Each covered the content of about a semester of college course.
Physics C uses calculus, though to a lesser extent than calculus based physics in college for physics and engineering majors. The two parts are mechanics and E&M, but each of these may not cover all of the topics in a semester of college physics course.
In terms of using AP credit for actual advanced placement in college, physics and other sciences are less reliable for this purpose than calculus and foreign language (i.e. colleges are less likely to offer advanced placement for AP credit in science than calculus and foreign language).
