Yup, we will find out on the 28th, but it will be published publically on the 2nd of May (so not long to go now!). Best not to worry too much, not much you can do about the layout of your exams; except accept it and take it as it is.
Though, I do hope your exams are nicely spaced out (cause that means the majority of mine will be too!)
There's not much we can in order to 'predict' the order of the exams, that decision it entirely up to the Board of Studies, but you can have a look at past timetable formats to get an idea. Though there does seem to be variables each year, depending on cohort sizes I would presume. (The more students in the subject's cohort means more scripts to mark, therefore longer time need to mark. (Thus the subject's exam would be placed earlier amongst the order of exams.) ~ I think.
