    If you underline it or write Ans. or something that indicates that this is the answer and not plain working, then they'll give the mark.

    Prediction of Grade Thresholds for May-June 2012!

    Because your expectations for the treshold are AWFULLY too high, AWFULLY. I mean Physics, Chem and Bio tresholds are 150 at MAX.

    Btw guys, are you sure that all the marking schemes are 100% correct? Since sometimes I'm 100% assured of an answer and it's still wrong according to the marking schemes.

    That's exactly the question, ventricles contract, and blood flows into the aorta, so it's ventricular systole.

    I'm happy you're not the person who actually sets the grade tresholds.

    Though, in ventricular systole, the semi-lunar valves are open due to the pressure by the blood, and the atrioventricular valve is shut to prevent blood to move back to the atrium.

    Are you sure this is diastole? Because diastole is when all muscles relax so blood flows into the heart. I think it's called ventricular systole. Thanks for your explanation btw.

    1 and 3, chlorine bleaches the litmus and sulfur dioxide is acidic so I think it should turn the litmus red.

    How do you know ?

    Total marks 200?

    If it were this way it would be awfully unfair, since paper 6 has been the easiest for all subjects, and it would get the least ratio.

    Well in that case my info is wrong :/ The concentration actually affects the pH. My understanding is that when water is added, solution becomes more dilute, therefore, less H+ ions are released in solution, therefore more pH. (pH is the measure of the amount of H+ / OH+ ions released in...
