Now that you have undertaken an AS -Level test relating to Topic 2, it is now time to
complete your biology profile. This will be useful in helping you to plan your
approach to revision.
The scale 1-5 should be interpreted as:
1 – Very disturbing
2 – Better than you feared but obviously time must be spent on this aspect
3 – Generally pleased but there are some problems to be looked at
4 – On the whole very good but some minor problems need rectifying
5 – Very pleased with this aspect, difficult to find any problems
Shade in the rows to give yourself an idea of your strengths and weaknesses and add to it in different
colours as you do your revision.
