About me.

As I wrote I have been a teacher of Russian language and literature at school. I conduct lessons in the 5th and 7th grade. My work is hard psychologically. I try to teach the children that I know myself. It does not always work. But I'm trying.

Just a few pointers:

The past present continuous is used – in contract to the present perfect- when we want to emphasise the duration of an action so your sentence feels incomplete i.e., you did not specify for HOW LONG you have been a teacher.

‘Conduct’ is not the right verb in this context. One conducts reviews, surveys etc., not classes.

Your sentences need to flow more – over use of full stops

A few suggestions:

A few words about me.

As previously mentioned, I have worked as a Russian language and literature teacher for many years.

I give lessons to 5th and 7th grade students (literally) OR I teach 5th and 7th grade students.

My work is psychologically demanding.

I try to teach my students – not clear so I have to guess – all that I know OR I try to share my knowledge with my students. While not always successful, I do (try) my best.
