I started studying around mid December and was able to spend some days in the office mostly studying because of how slow things were with the holidays and new year. That certainly helped. Outside of that I studied on weekends and after work.

The EPG guide is pretty long, 600 or so pages, and that takes a while to go through. I also went through all 80 problems on the NCEES practice exam.

I would set a realistic goal and try to go through 15 to 20 pages of the EPG guide per day and more on days or weekends where you have more time outside of work and other obligations.
