Planning what to read and when to read using timetable helps a lot by guiding you in the right direction.
There are times when you would have planned to read two courses and end up read one or even not completing it. This might occured sometimes but you have to find a means of covering that topic you left untouched.
For instance, you planned to read ABC and XYZ courses but you not read one that day. If the time you planned was in the evening, you can cover up the unread course by finding a leisure time during the day and read it.
Doing this will differentiate you from from failure.
* You can also plan your daily activities by writing down all what you have to do for the day in order of priority.
Uncompleted task should be done first the next day.
