I applied for my PhD at KCL in June and still waiting for their response (my chosen supervisor has already signed off on the proposal). I plan to start in Feb 2022. I'm an Indian student currently about to finish my Masters in the UK. I've been trying to look for funding but it seems most deadlines have passed. Can I still get funding from the university? Are there any other sources I should be looking at?

Which subject area? If you scroll to the bottom there appears to be one scholarship still open for Health Faculties or Faculty of Natural & Mathematical Sciences:
