Note: If you work at a computer, type a paragraph of plain text in English as a kind of self-adjustment. You can describe your day, your studies, your friends, whatever. This helps to activate the kinesthetic activity of the brain, responsible for remembering through physical actions. It is also useful to print the rules while learning grammar. Movements will help you to consolidate knowledge. In English there is a saying: “A picture is worth a thousand words” (“A picture is worth a thousand words” or “It is better to see once than hear a hundred times”). Describing a photograph or drawing, you engage the brain areas responsible for creativity. At the same time you can refresh your vocabulary by selecting a picture relevant to the topic that you will be studying. It is important to study English everyday. However, do not overwork. It is better to practice for 30 minutes every day than two hours once a week. Short regular classes are much more effective than long hours of study with long breaks. The habit of practicing every day will help to maintain the language skills in an active state. There is nothing better than learning English in a good company. You can do exercises together, conduct dialogues (in English!) And help each other in what is given more difficult. If among your friends you do not find like-minded people, sign up for English courses.
