If you are considering going for post graduation diploma courses (PGDM) or another part-time program then there are various factors you need to look out for.
All post graduation diploma courses involve managing racing priorities, but it is an even more valuable skill for part-time candidates. You are expected to be switching between mindsets & travelling constantly between home, university and work. Solve out ways to conserve time, like coordinating group project meet-ups before or after class & reserving books which you could pick up at the library once you are nearby.
I also advise thinking about when and how you work better. For instance, while working on the essays, I love to write in the morning time and read and edit in the afternoon time.
Setting a clear divide between professional/paid work & university work is not always apparent so I find it convenient to separate my assignments. It could be good to concede a degree of elasticity though.
It could be harder to build relationships with tutors and other post graduation diploma students when you need to head directly from work to class or fit in a productive time at the library. Spare time to socialise with the classmates, even if that only means a prompt cup of tea or lunch in the campus.
It could be beneficial to think forward. As a part-time post graduation diploma (PGDM) student, you could quiz your full-time colleagues about the modules you can take in near years. You would also get to see them go through exposition process & hopefully serve from their practices.
Even so, withdraw planning too far in advance. Try to acknowledge having more time to explore the interests & gain supplementary experience.
