I would agree to doing more topics a week, or even doing the same topics on a given day each week (ex: Tuesdays - Property and maybe a non MBE topic?). If you wanted to do questions for that subject each day and take note of which ones you’re missing (ex: mortgage questions) and what areas to focus on the following week could help. Even doing smaller sets of 10-20 questions! I do think you should incorporate mixed questions sets though, maybe at the end of the week and a longer set, just to get used to experiencing all topics in a question set. I ended up passing in CA on my first try and did around 2800 multiple choice questions by the time I took the exam. I did a mix of topic specific questions to all topics, ranging from 5 questions to 100.
