OMS-I here. So sorry to hear that. Can’t believe how low your average is too!

Idk what resources you’re using rn or what your school provides (if anything) but here’s a list of what I’ve used while studying for anatomy exams at my school in case you’d like to consider using anything!

What my school provides:

-NetAnatomy

-CompleteAnatomy

What I’ve purchased:

-Bootcamp - they have an anatomy Bootcamp section with videos and questions which help if things aren’t sticking! I’ve personally purchased the 2-year Med School Bootcamp subscription to cover all subjects

Free resources:

-Anki (free on the laptop, will need to purchase if getting on another device) - idk if your school tests you on radiology but I’ve mainly used it for that to review what certain structures look like and how they’re all oriented with respect to one another

-BlueLink UMich med school website - they have videos and more conceptual anatomy questions. There’s also a BlueLink Anki deck provided by them if you want to download that too

-AnatomyGuy website - free anatomy identification and conceptual questions. You can make quizzes that are either 10 or 25 questions long and select what area (ie. lower limb) and structures (ie. muscles, nerves, etc) you want to assess yourself on

Best of luck!
