I thought I did very well on this Data Response, but I got a 5 for IB grade. For the first question, I did fairly well, however, I missed out some of the points that IB wanted. For the second question, it was a disaster. I have mistaken PED graphs for YED graphs, this was the major reason why I did so poorly on this Data Response. Next time, I think I should practice diagrams more before the test.
