I've slowly been working my way through the Access courses and I'm up to Expert Level 12.
Things are now starting to get interesting, with the past three or four classes teaching me stuff I didn't know, or maybe did know, sort of, maybe a little bit, but I'm low in confidence with.
I have very little experience in working with reports, and aggregate queries.

I'm going to post a screenshot of a before and after type thing.
My basic, untidy, report versus a cleaner and tidier report after watching the lessons.
