I put aside a minimum of one hour a day, in the evening, while working. On the weekends, I set aside four to six hours each day.
I know there is a lot of material to cover and it can be a little overwhelming. I tried to focus on one topic at a time. For the longer topics/labs, I spent my time on one section or task. Also, don’t forget to take small breaks from studying so that you do not get burnt-out.
Hope that helps.
