You need to get your first semester's work done. You need to have no missed lectures and practice lessions to do this. You can close class absences. Write an essay (a brief overview) on a missed topic. Send your essays along with a workbook on this topic to the distance education website. For example, you missed the first practical lesson. You need to write a review on the topic " The microscope, its structure and rules for working with it". Then attach the file with the essay and the completed workbook for 1 lesson on the site in 1 topic. You can use the textbook and all the materials that are available on the site (lectures and presentations of practical classes, video resources).
