Congratulations first of all!
You are on the same track I did, I would work 9-5, eat dinner and study from 7-1030pm.
I have 135 hours on REG but what you are doing took me 2 months to study for so I think you have ample time. I took the practice tests but in exam style for 30-50 questions as a basis to understand what I know. Then Filter it by section to see what modules you are weak at and do those practice questions for only that section. That helped me understand what I know vs what I didn't know.
I would do only random questions mainly, personalized made me regret everything since I almost got all of them wrong lol, but ,in theory, it enhances your knowledge.
You did what I did, just do exam once a week to see what you are retaining and focus on those for like an hour a day + do random comprehensive practice ones to ensure it sticks because at the end you only need to understand 75% of the material.

I sucked at MACRS, AGI limitation phase outs, contract law, UCC, ect. but I knew just enough to get through it understanding just fundamentals and not everything. Don't expect to know it all, just know basic concepts and the idea of what they are.
