There are part-time postgraduate courses – many qualifications have that option so you can study and not have to give up your work.
Part-time course fees are less expensive for each single year of study, but may be more expensive overall as the course lasts longer.
Studying by distance learning is another option and can be cheaper.
Please see our advice on modes of study.
International students: If you require a Tier 4 student visa, you will not be able to study a part-time course.
