Please help - direct vs secondary admit CS major, mostly California schools

Thank you again for the links and your last comment of “it should not be difficult” was very reassuring to me! Grateful… for all your posts on CC!
The first link is much clearer to understand for me listing the foundation courses in a table / side by side.
Although I tried mapping the courses referencing the Sample Plan A, B etc. to come up with the 5 probable courses for first quarter, I am still confused on the loading as to exactly how many GE vs Foundation. Plus another course from the residence hall/hall that he chooses.
Guess it would be his academic adviser to assist. I should just let go and stop worrying! Son is very hardworking if he knows what he is taking in fall, he will head start in summer.
He is pretty much made up his mind to be a banana slug even though the school counselor thinks a smaller school is a better fit.
