@ProfessorPlum168 The Honors course description says “Honors Courses included in the totals below are taken in grades 10–12”, so only 3 years of courses. So if your total is for the whole of HS then it might not be that high.
A system with only 6 classes like most CA high schools would have a maximum of 36 semesters unless there is out of school dual enrollment. My kids had 2-3 UC Honors/AP courses sophomore year, then 4 APs in each of junior and senior year (i.e. 20-22 total). Even if you counted non-weighted AS/Honors classes you would only get to 24-26 in those 3 years. But from what I can tell, having 7-8 classes in a schedule (presumably therefore not an A/B day block with 3 x 1.75 hour classes per day) is more common elsewhere.
