tutes are not compulsory. unless the course allocates part of your final mark to tutorial attendance or lab work you wont miss much that you can't do by yourself. otherwise tutorial attendance only matters if your final result is borderline fail when they choose whether you get a pass conceded or fail.
for assignments and such, definitely talk to your lecturer. if you are lucky enough that the assignment is submitted online, you should be fine. Otherwise special arrangements may need to be made. As for quizzes and exams during that time, there are usually no supplementary exams except for the final, and even so you need a very good excuse (ie. medical reasons).
