I didn't run a statistic to compare sec 18-19 and twenty but I will say from observation that the participants were few unlike before, but I like it because it was more educative, I can talk about algorithm and hematology, in fact I would say I have learnt about Hematocrit and even the compound the Venezuelan parasitologist took the killed him, I didn't have to reflect back to remember this question but because I participated and read them thoroughly, they remain intact... Try and attempt some of the courses next season
