Cuny Assement Test (CATS)?

I got accepted into CUNY and now I’m invited to take the MATH3 cuny assessment test. Right now is spring break and I got their invitation a few days ago and the test is schedule tomorrow. I have only 3 days of study time for this test, fell like is a bit rushed. I am sure the test will be a walk in the park compare to the calc I’m doing now.
Is anyone else taking this test? What’s the number of questions + scoring? I can’t find a full test online. Also is untime, meaning there’s no time limits? Since is computer based, can I skip a question and go back?
