How can I efficiently take and organize notes for our upcoming 10-week internal medicine rotation's daily conference lectures?

I'm in my second year as a medical resident and really struggling with staying on top of note-taking for our daily conference lectures. We're about to start our 10-week internal medicine rotation and I know I'll have to rely on these notes for the upcoming board exams. I've tried using different apps like Evernote and OneNote, but I end up feeling overwhelmed with all the extra features and tags. I'm on a tight budget and can't afford to purchase any additional note-taking software, so I need something that's free and effective. I've also tried the Cornell Note-taking system, but it doesn't quite seem to be working for me given the large amount of information we're covering each day.
