How does it work?
Spread your hours and give yourself more time on tricky subjects. It also means that you won’t have to work so many hours in a week if you want to stick to the 300 recommended study hours.
For example, you could reduce your personal study hours from 15 per week to just nine hours per week.
Or if there is a particularly tricky subject, you have the time to dedicate more hours to it, without neglecting any other part of your studies.
