I hired a tutor to help me with a calculus problems I didn't understand. I was a first time user back then, so I was unsure about understanding how the whole tutoring dynamic works, but I was desperate to get some help. I have a hard time talking with people, so asking questions via messages was much better for me. Now I also ask questions about biology, chemistry sometimes and look for my first tutor when it comes to calculus' homework- I rather be in the comfort zone.
