    Basically: ( I will have another try) So, your raw mark translates into letters. For some subjects you don't need 90% to get an A*, all you need is, say 75%. But the letter grade also translates into a Uniform Percentage: An A* for Subject x represents a 90% even though the person only scored...

    I am also confused and nervous, but I think those numbers are this: PERCENTAGE UNIFORM MAKRS. From the Syllabus of other courses, I will copy and paste: • A candidate who obtains... ... the minimum mark necessary for a Grade A* obtains a percentage uniform mark of 90%. ... the minimum mark...

    I live Brazil, got A* and 100% for all those you mentioned. From what I've read, I think it is a percentage uniform mark so, for example: 20 - 30 marks in Physics is a B, 31 to 40 A and 41 to 45 A*, but the test is out of 100. Whoever scores the minimum mark for an A* is awarded a 100% Uniform...

    The numbers next to the letter grades are percentages? Because I am pretty sure I didn't get 100% on some tests they say I did.

    Chemistry Paper 3 Discussion

    Hi guys, anyone wanting to discuss the paper? I am interested in knowing the answer to the moles question: I got, in order: 0.08, 0.04, 0.04, 9.52, 0.08, 0.05 What about you?

    0625 Physics Paper 3 Discussion

    If you mean the one about gamma beta and alpha radiation... The ray B if I'm not mistaken was Gamma due to the fact it was not deflected by the magnetic field and it had the greatest number of counts because it has the weakest Ionizing Effect. The one deflected upwards was Alpha, as you could...

    "The 2nd question The force needed is " Friction " .................Actually friction between tires and track provide the needed force to make the car move in a circular direction And It acts Towards the center" Yeah, saw that in my textbook today

    0625 Physics Paper 3 Discussion

    It was worth two marks... So I put current gradually decreases (ammeter reading gradually decreases) with time as the capacitor charges up but I am not sure if they wanted us to mention that the reading would eventually become zero for the two marks, maybe yes

    Yeah... I put force outwards from the center...

    0625 Physics Paper 3 Discussion

    I remember the velocity one yup. Got that one right. But I think I put the force the car needed to make was towards outside the circle and that the force was due to the car's acceleration...

    I think those are all my doubts... I know that the part I really messed up with was the second question about circular motion... but I can't remember what was asked
