Finding the Office Hours
All my courses this semester have office hours - time the professor dedicates for students to ask any questions. Professors are domain experts and have been studying their particular field for years. Thus, office hours are an incredibly valuable resource where one can ask professors anything and everything whether related to their field of expertise or not.
Now, with the internet, most people have emails and with a well written cold email everyone’s reachable. And more often than not, most people are willing to help out.
Whether it be networking towards a job, learning from a domain expert, or finding a mentor, the office hours you’re looking for is out there, you just got to look for it.
