I'm new to Stack Exchange and I apologize if my etiquette on posting a question on this platform is "wrong".
So I took a course last year with a professor who was exceptional on her subject that gave me a better perspective on the subject, and ultimately got me a really good internship in the same domain.
How should I write her an e-mail (without being awkward) with a thank you note, as I wasn't in touch since the end of that course?
