Manipulating and solving linear equations: extremely important and arise in many different parts of science; make sure that manipulating simple equations becomes second nature
Exponentials and logarithms: important for radioactive decay; acids and bases. Trigonometry: Almost every year force questions show up in GAMSAT for which you will need to know basic trigonometry – sin, cos, tan and the difference between radians and degrees.
Basic probability: as applies to genetics, For example: if you cross X with Y what are the chances of getting a Z
Unit manipulation: Manipulating of equations. Be aware of the power laws when multiplying/dividing quantities, for example: xy/y4 = Xy-3.
