How can I best prepare for an operations internship at a small hedge fund?

Hi there, I'm a mathematics undergraduate in Singapore and will be embarking on an Operations Analyst internship in a small hedge fund (think 5 - 10) people - this will be my first "finance" related internship.

I am trying my luck if I can reach any people that work in Fund Operations that can advise me or recommend me any online courses or books I can pick up to better ease into the role - I want to perform well for the internship, and eventually assimilate into the role of a full-timer (it is a 6-months long, full-time internship). As the firm is really lean, I am expecting to need to wear a few hats and be up to speed with learning how they do things.

I am currently working on Capital Markets & Securities Analyst course by Corporate Finance Institute, but was wondering if there were any other courses or material that are more specific to a fund operations role.

Thank you so much.
