I did Changes in Medicine and Vietnam. I was really happy with medicine questions but for question C I knew I should've done the one with school medical service and public health act 1848 but I did the x-ray and second world war with my third one being first world war. I hope I did well on that. For question A I said 2 differences were that Florey and Chain Mass produced and the second that Florey and Chain were the first to use penicillin for medicinal reasons unlike Fleming. For part B I talked about Germ Theory and About John's Snows Broad Street Cholera Research, and For question C Like I said I did technology, First world War, Second world war.
Idk if anyone else did Vietnam, but for question A I did Johnson and I talked about operation rolling thunder and gulf of tonkin resolution. For question B I said similarity is that they agreed that the US was training South Vietnamese troops but they disagreed as Source A had no mention of north vietnamese guerilla attacks. For question C I agreed with the interpretation and for my own knowledge I talked about sects crisis, Law 10/59, Buddhist Monk Crisis, and Strategic Hamlets.
