This may be caused by two factors.
Firstly, the distance that a student specifies as being comfortable for him to travel to is taken into consideration. If you wish to travel further, you can change the distance you are willing to travel by logging into your profile, going to 'Enquiries', selecting 'Enquiry location' and then entering the distance that you are willing to travel in KM.
Secondly, we only match Tutors with students based on the distance that the student is willing to travel. This may cause Tutor's not receiving enquiries from students who are not willing to travel the distance between their locations.
