Take the free PrepLion diagnostic (15 minutes). You'll immediately see your pass probability, estimated hours to pass, and which topics you can skip. Focus the rest of Day 1 on your weakest unit.
Practice only the topics marked 'Focus' on your topic map. Use Sage to explain anything confusing. Complete 30-50 targeted questions.
Take a timed mock exam. Check your calibrated CLEP score. If you're at 50+ (passing), you're ready. If not, focus one more session on your weakest remaining unit.
