Clean Grammar

The book is addressed to foreigners studying the Russian language from the level of TRKI-1 (repetition and control) to the level of TRKI-2 and TRKI-3 (in some cases TRKI-4).
The book presents the most complex grammatical topics: cases, aspect of the... verb, verbs of motion, participles and gerunds, prefix verbs. Exercises are given according to the principle of increasing difficulty. It is important that, along with grammar instruction, work is being done to expand the vocabulary (from a minimum of 500 words to 5000 or more units).
This organization of material and the presence of theoretical commentary will help those studying the Russian language independently. Control exercises and tests correspond to the format of certification tests (TRKI) and come with keys.
