In Aleks they have a really great system for typing in complex math equations. You can even write superscript and subscript. If we had something similar to that, it would make it easier to explain exactly what type of problem we need help with.

This isn't against the tutor at all. But I really think you guys should have your tutors learn to be extra patient with students who are learning disabled like me. I had to bring up my learning disability in order for it to be easier for me to understand what I am doing. Sergio was great by the way.
