It depends on your standard. If you are comfortable with manipulating formula i.e. speed = distance divided by time, what is the distance travelled in 2 hours at 60kts - that sort of thing.
Pythagoras theorem and very basic trigonometry related to right-angled triangles is as complex as it gets.
Enrol on your DL course, see how it goes and if you have trouble, contact your school. They will give you help via email or over the phone. If you really want one to one tuition, check the local paper for Maths tutors.
