Over 20 years ago, my med school was among the first to offer online lectures (anyone remember RealPlayer?). I can’t remember if they were livestreamed but they were certainly available immediately after since we had to be able to keep up.
In addition, for probably decades before any online courses, med schools had note taking co-ops in which one student was pre assigned for each lecture/topic to produce high quality notes - not what you scribbled in lecture, but an outline/bulleted Word document with illustrations and references - that could take hours.
I was a “nontraditional” med student coming from a brief career in bioengineering. With all that available, in hindsight I felt like I could have kept working part time for the first 2 years instead of taking loans!
I did end up getting a grad assistantship research position based on my previous job, which had multiple benefits - CV building for residency, hourly pay, and a tuition credit. I had plenty of time to do this…I did still attend lectures most of the time though.
