Good preparation for universities. Teachers present their subject in an accessible way. I took chemistry, biology and Russian classes. At the end of the year, they will work with assignments from previous years from different universities. You can additionally approach before the lesson and ask for an explanation of some point. As for taking exams online, it is better to take them from home (there will be frequent problems with Internet connection). But if you are applying to SibSMU, then a commission may come to the city and then it is better to take exams from here.
