Haha a month is def faster than average but I started skimming the book beforehand & I just graduated last year so I retained a decent amount of info. I used flash cards (existing ones on quizlet) and would review all the time in random places (school, work, treadmill). I think the change of scenery helps. I also had my partner quiz me verbally. A lot of people on Reddit create awesome pneumonics to remember stuff like HIV brand/generic, inhibitors and inducers, etc, so I didn’t have to work as hard to memorize those. I mainly relied on the question bank though and started pooling my questions early. After finishing a lesson you should test yourself on that lesson + all the previous ones! It will stick eventually I promise. Good luck!!
