Choose a tutor whose qualification and experience commensurates your requirements. A tutor holding a master degree in Mathematics may not necessarily be well suited to teach secondary Math due to the large disparity in profoundness. Fresh 'A' level graduates with good relevant grades may be a better fit at a much affordable price.

TIP NUMBER #2

Avoid hiring a "Jack of all trades". It may seem economical to hire a tutor who  - at the same price - can teach many different subjects. Pound for pound, the quality will most likely be compromised. Get tutors who specialize in their respective discipline. It is with good reason they specialize and the quality very often stands out.

Start early! Do not wait till the last moment before engaging in a tutor. It takes a while for the tutor to grasp a student's understanding of a particular subject, and his style of learning. Instead of cramming lessons x3 a week two months before major examination, it would be wiser to spread the lessons x1 week 6 months before their examination.
