It is based on your subscription. If you bought the 30-day then you won't have an assessment. Only the 60-day and higher have the self-assessments. They're pretty much 75 questions on test mode and at the end, it will give you a test analysis where you find out your chance of passing: low|borderline|high|very high. My subscription came with 2 assessments and I took the first one 2 days before, and the 2nd one, 1 day before the exam. I recommend doing 75 questions on test mode and reviewing the rationales after. GOOD LUCK!
