I had Mr. Peralta for double accel. His class was my favorite and it was super fun. I like the challenging math problems he gives because it is something that doesn't happen in most school math courses. He has a very unique teaching style. He is always in the front lecturing and is a very hardworking and dedicated teacher. The exams are usually a mix of easy and challenging problems but they aren't to bad. The midterms and finals are usually easier. Good luck!
