You must choose your courses from among all the courses of your previous Personal Study Plan.
Please note that some compulsory courses may have
pre-requisites (courses which have to be taken before others). This means that you cannot add certain courses to your APSP without including the pre-requisites first. The pre-requisites are listed in the curriculum of your
degree programme. Make sure you read it before you create your APSP.
You can add new courses (belonging to the next academic years) to your APSP, only after having included all your incomplete courses from the previous years, except for your third-year free choice credits (optional courses) that may be eventually taken in year 2.
If you still have some pending exams, you are not allowed to create an Annual Personal Study Plan without including any credit.
In any case, the system prevents you from creating an irregular APSP in which the pre-requisites are not respected. A warning message tells you which courses must be included before others.
