Express preparation for the OGE in chemistry for grade 9 - free course from Foxford, training 22 lessons, date: December 4, 2023.
Miscellaneous / / December 07, 2023
No panic or stress
All the necessary topics and tasks for successfully passing the OGE are in the course program
Systematization of knowledge
The program will help you sort out all the high school topics in chemistry.
Practice OGE tasks
Solve unique test versions of the OGE, compiled according to the recommendations of FIPI and find out your readiness
Teacher of Olympiad Chemistry at the Sirius Educational Center The average result of students on the OGE is 4.7 out of 5 Co-executor for state grants (RSF and RFBR)
The training is suitable for anyone who wants to get a good certificate
The course is suitable for students who want to repeat all parts of the OGE in chemistry: test, part with a detailed answer, experiment Preparation will help you get a good certificate, which is important for entering a specialized class or college
Accelerated preparation for the OGE in chemistry
The course briefly examines the theory of grades 8-9, and also studies topics in general and inorganic chemistry, qualitative reactions. Experiments are demonstrated in class and conducted by students in a virtual laboratory
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
