EU nationals taking an undergraduate course in Britain contribute the same amount as UK residents, although they also receive free tuition for first degrees at Scottish institutions. Non-EU international students , who are not settled in the UK, generally receive no help unless they have a bursary or scholarship, and have to pay the full international rate charged by the institution. Contact the undergraduate office of your proposed institution for more information. Each year, these bodies distribute a limited number of studentships, which cover course fees and a maintenance grant towards the cost of living. Competition is intense and even students with first class honours degrees are often unsuccessful.
Institutions sometimes have their own studentships and bursaries for postgraduate students.
You should contact your chosen institution to see if there is one for which you may be eligible. It should be remembered that many postgraduate courses can be taken part-time, allowing you to work whilst studying. More information on funding postgraduate studies is available from CSU Prospects.
