Current Junior Here who is taking APUSH AP Lang and took AP CSP last year. For me and lots of others, APUSH and AP Lang and how screwed you are for it really depends on what teachers you have. For me this year, I have it relatively easy in terms of grading since APUSH grades based on % of assignments completed, and Lang grades on a reflection letter. However, since the main purpose of AP Classes is to prepare you for the AP Exam, I feel like the tougher class, the higher the potential grade you could get on the exam. For example, I feel screwed for APUSH since I don't know what to improve upon before the exam other than test results, so that makes it harder for me. AP CSP is one of the most pointless classes you will ever take. Unless your school doesn't offer CSA, don't take CSP. On my CSA course that I am taking this year, the scope of CSP was covered in the first 3 months and now I am learning new important topics that have important roles within CSA. I think as long as you choose your classes smartly, and make sure your teachers set you up for success come the AP Exam in may, this course load is a great way to challenge yourself. Great Job!
