I took a diagnostic a few weeks ago but haven’t taken any full PTs since then. Right now, I’m only partially through the curriculum, I’ve made some progress in the Logical Reasoning section but haven’t touched Reading Comp yet.

I’m tempted to start taking full-length practice tests to begin building endurance and test-day skills, but I’m also worried it might be too early. I don’t want to waste time on PTs if I’d be better off continuing through the lessons first.

When should I start taking full PTs?
