Verb conjugation of "transplant" in English

Thanks again for your time. I attached my avatar, it is very similar to the previous one. I have guided the development of the website, and I feel free to share my knowledge with others.
I remember once again how I failed as a student, mainly in French class. Since I have lived in Russia, it was not easy to learn other foreign languages. The alphabet is also different.
Now I am learning by other means, such as reading and writing. I can not begin with conjugation training because I lack the basic knowledge. How are you learning at this site and which is your best lesson?
