By past papers, from which year you started doing? 2001? Can't find unit 3B paper for 2001.
From which year did the whole unit 3B starts?
edit: Okay, so it's from Jan 2009, right? But can't seem to find the paper. Could only find June 2009 onwards. :/
ps: We only have to study the 9 core practicals, right? Which are:
1. The effect of caffeine on heart rate
2. the vitamin C content of fruit juice
3. The effect of temperature on membranes
4. enzymes concentration and rate of reaction
5. observing mitosis
6. totipotency and plant tissue culture
7. the strength of plant fibres
8. investigating plant mineral deficiencies
9. The antimicrobial properties of plants
Right? :s
