I'm feeling a bit uneasy about cutting large pieces of plywood accurately, as my smaller cuts with the table saw work fine, but the larger ones tend to be a challenge. I've tried using a circular saw with a jig on the floor, but I still find I'm a tiny bit off with my cuts. I'm looking for tips to help me get better and more confident in my cutting skills, especially for those bigger pieces. Thanks for any advice!

Consider building support tables for your plywood—about 18x18 inches on each side, matched to your saw height. The in-feed can be slightly taller and the out-feed a tad shorter to help balance everything. You could even make a huge table if you have space, but saw horses can work just as well and are easier to manage! Also, trimming new sheets slightly helps, as they usually aren't perfectly square from the factory.
One handy tip is to make your rough cuts on the floor first and then finish them up on the table saw for precision. Also, you can build a circular saw guide jig, which acts like a budget-friendly track saw. There are tons of YouTube tutorials that show you how to do this. Just clamping a straight edge down on your plywood can really help with accuracy too! If you're feeling up to it, you could also invest in a track saw—it’s unbeatable for cutting full sheets accurately.
I've seen those jigs in action—they really do work wonders for accuracy!
If you're serious about cutting full sheets, a track saw is worth the investment. It’s the best tool for making precise cuts solo. But if you don’t want to spend right now, practice is key! Pay careful attention to what goes wrong with your cuts. Is your jig shifting? Is your saw straying? Figuring that out will help you improve.
Exactly! Understanding your mistakes is half the battle!

I did the same thing with sawhorses and it made a huge difference for me!
