Welcome, this forum was honestly one of the more useful parts of my own prep, so you picked a good place to start. I studied for about 5 months while working full time, and the biggest lie I told myself early on was that more hours would fix everything. What actually moved my score was being honest about which section was dragging me down and hitting that section hard for a few weeks instead of spreading myself evenly across everything.
Consistency with a full time job is less about willpower and more about protecting a fixed block, even 45 minutes, and treating it like a meeting you can't skip. Concept grouping helped a lot once I hit a plateau too, instead of random mixed sets, I'd run just rate questions, then just assumption CR, so I could see which specific idea was actually tripping me up rather than guessing from one jumbled score.
Ask specific questions here as you go, people are generous with detail if you give them something concrete to respond to. You'll find your own rhythm faster than you think.
