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 !!!

How does A* at IGCSE work? Is it by set grade boundaries or is it like first 20% get A*. So if for instance Bio P3 was super hard, maybe I stand a better chance of getting A* if everyone else found it hard?

The top 10th percetile get A*s
If it was a hard paper then chances are that 10th percentile will be big.

What's 10th percentile, and how does that relate to the 21.666666667% you worked out? Is the 20% of all candiates get A* or what, and what's percentile. Sorry for being dumb :(
WARRIOR:
AAADII..EHM ( i need u to imagine over here )
look if there is a ciruit with a resisor in series and after the resistor comes two PARALEL resistors .
Is it true that if the series resistor has a higher resistance that both the parallel , the current goes thro sreies resitor first?
because the voltge has to be used up in teh series resistor so that we could calculate the voltage around the parallel ones?
