Reasoning in biological and physical sciences

Maths is not directly tested in GAMSAT but the exam does assume a certain level of mathematical ability. Many questions will involve mathematical concepts, be they logarithms, graphs, or statistics, so it is essential that you are comfortable with maths.

# Measurements

Be able to interconvert between units

Know that 1mL = 1cm3

Know scientific notation and be able to apply it

Understand each of the units you work with

#

# Operators

Know the order of operations (**B**rackets, **O**f, **M**ultiplication, **D**ivision, **A**ddition, **S**ubtraction)

Understand and apply exponents, e.g. 10-6

Work with squares and square roots

#

# Equations

Know and interpret fundamental algebra (remember: what you do to one side, you must do the other!)

Be able to manipulate equations algebraically (**HINT**: many physics and general chemistry problems in GAMSAT that involve calculations can be solved by equating two equations, a frequently occurring example of this is equating potential energy to kinetic: 1/2mv2 = mgh

Translate information in passages from words to equations

Manipulate the units in equations as needed

#

# Statistics

Know the basic concepts of probability, these will most often occur when faced with genetics questions

Understand and apply mean and standard deviation.

#

# Trigonometry

Understand and apply Pythagoras’ theorem

Manipulate cosine, sine and tan ratios when they appear in equations

Be able to work with angles and degrees (most trig measurements will be provided for you

#

# Logarithms

Understand the components of a logarithm

Apply logarithms in the context of pH and pKA

Interpret graphical representations of logarithms

#

# Graphs

Interpret and compare different forms of graphs

Know the different graph trends (linear, exponential, sigmoidal) and understand what they imply about the data

Know the significance of the area under a curve e.g. for a velocity versus time graph the area under the curve signifies displacement

Be able to calculate gradients and tangents to a curve

Predict how a change in conditions may affect the shape of a graph, e.g. in biology an increase in heat may shift the curve to the right
