This varies from student to student. Most of our postgraduate students have jobs, families, social lives etc which they juggle to complete the course. We find that many students become addicted to the course spending as much time as possible to get the most out of it.
Typically, we suggest aiming to login on to the course website daily. (Then when you miss a day it is less of an issue). High achieving students will typically spend 1-2 hours each night after work and then set aside additional time at the weekend. You should expect to spend a minimum of 10-15 hours on the course each week of the module.
Applicants who wish to log in once/twice a week should not do this course, it is important to remember that you are undertaking a postgraduate course and as such you can expect to work to achieve your valuable qualification.
