If you ger 71 in 3H and 82 in 4H would that be a star?

nope would be a good A, but i doubt an A* as that averages out to 76.5/100 and you need atleast 79/100 averaged to have a shot at a possible A*. For safety - 81/100 averaged will 99% get A*

sorry, I assumed people would not have had difficulty with those ones. Unfortunately I have some revision to do now so I won't be able to upload those I'm afraid.

NOTICE : I left out question 17 (Histogram because I kept getting 190 patients even when doing the correct method that I used in the exam). The answer to the first part is 18% and the answer to the second is either 190 or 200 but I am not sure so I didn't upload it in case it confused people. Hope everyone did ok :smile:

Will they give marks if we draw a graph as uglier as that? I thought it takes take 10 mins to draw a graph (so untidy I am), but will they give marks?
