I would take a break from exams and really focus on honing in on individual question types. With your tags being all over the place this means you aren't necessarily consistent in a particular area. I would suggest working on the individual types, blind reviewing, and making sure to identify the conclusion and premises in all stimuli and then breakdown each answer choice. Writing it out will help train your brain. Additionally, drill increasing difficulty once you are mastering the lower difficulty. This will help create a stronger foundation. Also make sure that the answer choices actually resolve the issue in the stimulus and try to breakdown and properly identify the elements while also working to get faster. I would then do individual timed sections to make sure you keep up on timing and can then better assess weak areas and then add back-to-back sections and then exams so you can build endurance and accuracy
