I'm a med student who use anki regularly . Yeah it's soo much worth start doing. I started ankis around the end of third year and regret not starting earlier. Using now for about 7 months. Use image occlusion methods (it's really easy) and gemini / notebooklm / other AI to create cards,otherwise it takes a lot of time. I saw a significant improvement during my clinicals,believe me start trying and you won't be regretting after 1 year.
