I did chemistry last year and got an A*, lost surely over 7 marks in p6, 18ish in p3, and around 2-3 in p1.
Don't Worry, the chemistry curve does wonders =-P

It was Easy, the last question answer was :-
1. Place each Corrosion inhibitor in 3 test tube of equal amount.
2. Take 3 steel nails and place them in 3 water bowl.
3. Place each inhibitor in bowl.
5. Leave it undisturbed for 3-4 days in presence of air.
6. After 4 days, Remove the rust which will be Flaky brown solid (FE2OH3.xH2O) and dry them and weigh each of them.
7. The one which has more weigh will be least effective corrosion inhibitor and one with lower weight will most effective corrosion inhibitor.

Well, don't worry about the sciences. The curve is always low. According to CIE statistics most A*s are usually scored in scientific fields =-d
