Water defo. Cos inter-molecular bonds of water is slightly weaker than solids, so they are able to expand more (the molecules).

Okay people here is a morale booster :
Statistically, in May/June of the past three years - 21.66666667% of all candidates got an A*. This is an average I worked put from offical data.
Statistically, in Oct/Noc of the past three years - 18.25% of all candidates got an A*.
Thus WE have a better chance of getting an A* than our winter session counterparts.
People lets do this and get it right !!!
