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.
Guys, don't stick your head in this organization. Before contacting them, contact the university where you are applying. You just give them 80,000 for renting a computer, they don't want to be responsible for anything, if there are problems with the procter system (the system that controls the applicant during the exam) or lack of communication (Internet), then these will be your problems. They'll just spread their hands. They don't care how your child passes the exams. There is no help from them. Now many universities take exams online, contact them, their admissions committees. Don't hesitate to call. They will help you more, isn't that a Prospect. I do not advise you to contact them.
