Students of 5 grades already know what is the subject of "Biology". As part of the course, they have already studied the species of living organisms, touched on the cause of their diversity. For children who have learned the material well and who want to repeat the topics, we offer to pass the school biology Olympiad for the 5th grade. If the child doubts his / her abilities, he / she can solve examples of tasks with answers. They will be a good preparation for the student and allow him to pass to the municipal level.
