I’m kind of lost in the LingQ environment. I don’t know how to do activities like writing, recording audios. But one day I will learn.

You can submit writing for correction to a tutor on the Tutors page. You will see correction rate for each tutor there. You will need points to submit writing.
What you can also do is to submit open request on the Community page, Writing Exchange tab, and other members will correct it for you.
