The Knewton course
is self-paced, so you can put in as much or as little time as you want per week.
The Complete Prep option consists of on-demand lessons which you can proceed through at your own pace, and gives you unlimited access to our materials for 4 months, so you will want to finish up within that time.
The Premium Live option gives you unlimited access to our materials for a full year, and you can also attend up to approximately 24 hours of office-hours style live workshops each week. Since these are of a non-linear nature, you can opt to attend whichever sessions fit your schedule.
I hope this helps. Please be sure to let me know if you have other questions.
