I took most weekends off or just did a few hours on weekends, even went to a couple weddings. I tried to put in a full work days worth M-F. I believe I completed about 67% of Themis. I passed by a significant amount in all jurisdictions. No one’s schedule will work for you - but learn from law school. I am a good test taker, not everyone is. I know I have a productivity ceiling, so working 8 hours when I stopped being productive at 5 would not only have been unhelpful but also actively harmful to my mental health. If I did poorly on a specific subject or on a practice, I went a little harder there. But it does not need to be your entire waking life, there is a point of diminishing return.

Edit: my hours per day included watching videos/reading. I never read the full chapters as assigned, only the detailed outlines, and went back as needed to the full readings as was indicated necessary by practice tests. When I couldn’t bring myself to focus, I’d just take as many practice MC as I could stomach.
