This is my first post on my journey.
I gave the diagnostics test a go for an hour on non-timed mode and felt that it was really painful, since I wanted to use it as a way to see what it felt like to do a CAT.
I already noticed that I spent way too much time, didn't step through the questions enough, don't remember formulae to solve the questions etc etc.
Also, doing a diagnostic test after work is a gruelling experience, especially if you start at 9pm.
I think tomorrow I'll start reading through OG12.
I've got an exam date booked for 28th April. I think if I invest and stay dedicated I can succeed.
