Preparation for Olympiads in chemistry for grade 9 - free course from Foxford, training 33 lessons, Date: December 5, 2023.
Miscellaneous / / December 08, 2023
Who will benefit from the course?
A course for students in grades 8-9 who want to study the subject in depth and prepare for Olympiads in chemistry.
What knowledge does the course provide?
The classes cover all the main sections of chemistry found in Olympiads. Also, much attention is paid to solving problems from past Olympiads.
How is the course useful?
The course teaches you to apply different approaches to solving non-standard problems, see their structure, and think creatively, going beyond the school curriculum.
We manually check samples and homework
We do not leave the written part assignments for self-testing - this is done by OGE experts.
We check “for real”, like in an exam, and as a result you receive detailed feedback. All this is for the sake of speed of preparation and your results.
A personal curator will answer questions within two hours, 24/7
The curators understand the program and the subject, so they can easily answer your questions about the course and homework - at any time
They know well how difficult it can be to prepare and understand your worries.
The most important task of a tutor is to help you cope with stress and fear before exams
The lesson lasts 3 academic hours.
