Information Overload

I’m in training and just wondering if the PowerPoints are super duper important to like sear into my brain ;; we obviously can only train on the pcs but I feel like there is just so much jargon and percentages and stuff and I’m worried that I won’t remember it :( But when we watched a live call there wasn’t anything pertaining to what we’d learned yet except the first portion which was about the programs you use which makes sense but all the extra information wasn’t :(
