Been planning to do CASP for about 8 months now, but work and life got in the away of prepping. So I kept pushing it back, month after month. Until the PV scheduler told me that the voucher I used to create my exam appointment had a limited lifetime. So I set up my final appointment for the last day the voucher code was valid. Procrastination is my superpower.

I had bought the Abernathy book, but due to poor time management I only read chapter 1 before the exam. I did maybe 100 or 125 questions from the Pearson practice exam question bank, averaging about 85%. Fortunately, I had knocked out SY0-401 a couple of months earlier. I mainly used the Sec+ book by Prowse, and the Pearson practice exam questions.
Since I had no expectation of passing, and only there to see what was on the real exam, I was very relaxed during the test. The one PBQ that I know I whiffed on was a Linux command line thing, which is embarrassing since I have RHCSA. In my own defense, in my job of the last few years I haven't touched Linux at all, except for a Kali Linux demo here and there.
I'm guessing that passing was a 750 and I earned a 751.

So, recommendations:
- hit your Sec+ book & practice exams HARD before starting in on your CASP materials.
- make sure you understand the risk management calculations. don't just memorize the formulas, understand them.
- know your Windows and Linux command line.
