Yep. Signed up for just a Saturday. That went fine. Practiced positions etc. now that I knew what they looked like. Practiced dry firing the timed stages with a timer to shake out any bugs in terms of getting into position, doing the reload, shifting NPOA, etc. Signed up for just a Sunday - happened to be a different instructor. Shot as high as a 228.
For context - I'd barely shot a rifle before the first one but I compete with handguns so a lot of the material was either identical or very similar (trigger control is pretty much trigger control). My understanding is it usually takes more like 2-3 weekends to break the 210 barrier.
