When I tried to upload a pdf, it wouldn't allow me because it was bigger than 1 MB, and I had to find an alternative way by using a screenshot. I would appreciate it if you could maybe allow the service to upload items bigger than 1 MB.

I wish you all had a skype kind of thing. ITS WAY TO HARD to explain everything by just typing it. I am failing my 8th grade science highschool course and it would be great if you added a skype thing, but without faces, only voices. i'm dissapointed in tryig to find all these youtube videos from like 2006 for science and math help. tired of it. but nice site.

My tutor did not rush the session, and made sure I understood all the concepts before further progressing on to an another part of the problem which was very helpful. Other tutors sometimes rush very quickly or say they have to wrap up this session but my tutor took the time I needed to understand this which is appreciated.
