Hi, I have not done NBDE part 1 but, I'd say make studying a routine or part of your day would be a good thing.
If you are reading something and you not dominate it, try dominating that section (for example, I, myself never mastered the anatomy of the Common Carotid, External, internal Branches. I decided I would master it. It took me around 1 - 2 weeks doing hard work, reading, looking at different anatomy books, and still mastering it, it is not an easy task. At the same time... right now.... I would feel very secure against a head and neck Vascular question).
Hope that helped, and if not, I think going deep and a constant pace will do it at the first try. 🙂
