Postgraduate courses include postgraduate diplomas, master’s degrees, and doctorates (PhDs). Usually this is the step after your undergraduate course since you will need one to progress to this. A postgraduate diploma is a shorter qualification but at the same academic level as a master’s degree. The difference is that the first is made up of 120 credits and the latter 180 credits. This can take 1 or 2 years if you study fulltime, more if you are studying part-time.
So, if you want to specialize in a subject this is the way to go, because you will develop and further your already awesome skills and you will gain a deeper understanding of your study area.
Once you are finished you can apply for jobs or if you want to conduct a deeper research on your chosen subject you can pursue a PhD, you will be awarded a doctoral degree. To do that you need to develop
extensive and advanced work that will make knowledge contribution to your field of study.
