The entry-level courses (such as Certificate in Astronomy) require Maths at GCSE grade C or equivalent qualification. The modules assume general 'high-school maths' such as the ability to use a scientific notation and powers, perform calculations with a scientific calculator, rearrange simple equations, logarithms and simple trigonometry (sines, cosines and tangents). If you have not studied for some time, you may like to refresh your knowledge. If you do not have a formal Maths qualification you should contact the Course Leader for advice.
