Quizlet is something I used a lot to study terminology. A quick google search with something like "intro to medical terminology quizlet" will yield you quite a lot of results.
Another thing that was really drilled into me during a Coursera Medical Terminology course was being familiar with Prefix, Root, and Suffix words pertaining to medicine. There are a lot but some are much more commonly seen than others.
-itis: inflammation
-ectomy: cut out or remove
-megaly: enlarged
-otomy: to cut into
etc. etc. etc.
HERE is a link with some of the most common medical prefixes, suffixes, and terminology.
THIS is the Coursera course I took before applying to be a scribe. I had 0 medical terminology experience so this helped me. Its free. You can pay for a certificate but it's optional.
Ummmm, I can't think of much else at the moment. Good Luck!
