The tutor allowed me to go through my own thought process when I wanted to walk through my steps on certain topics I did not feel confident on. Also, he helped a lot in explaining on what I was confused about.

Audio quality wasn't so great for this session. Maybe because I wasn't wearing headphones, but still. Also, why is the font for this the default Courier New? Haha, not a big deal but just a bit weird.

I think you should add specific topics for the subjects as a dropbox. Some tutors sometimes don't know the topic of the subject. Ex: Chemistry> stoichiometry, Moles, Chemical and physical properties, balancing equations.
