I'm taking my first PCAT in January. My weakest area will be quant, and I'm sure I will need to skip the harder calc problems and save them for last. I've never taken a real test on a computer before - I graduated from college 15 years ago. I have taken the 3 Pearson practice tests, so I'm wondering if someone out there could describe for me how the real test is the same or different, specifically how to skip problems and make sure I know how to quickly get back to them. I don't want to accidentally leave any questions unanswered. Thanks in advance.
