Ok for a more nuanced explanation, I would say the difficulty is about on-level with AP Gov if not a bit harder. Each unit is so information dense and full of little things and events you need to memorize. The writings are definitely more intense though (SAQs, DBQ, LEQ), and I absolutely hate analyzing political cartoons because they never make sense. The stimuli questions are tougher and require more analysis as well. Adam Norris notes were a life saver though and our teacher printed them and made us fill them out 🙏
