Help finding inexpensive courses & upper level

[Ideas]

Davar Academy has Management Information Systems and about 4-5 UL business courses. They are NCCRS so it depends on what school your child is attending. TESU takes NCCRS but many schools don't.

Other than those, many courses in your first list are lower level courses by their nature (intro or principles courses, the first two accounting courses, etc).

Study.com is expected to get approval for their Data Structures course but it's not yet available. They do have a UL database course (and are expected to have another for credit), Computer Architecture which is UL, and Systems Analysis & Design which is UL.
