I work as a private tutor, I teach foreign students an English language so that they have the opportunity to go to college. Many students find it difficult to write an essay. Especially a biology paper. Because there are complex topics and there are many terms. I am often asked to check such essays and I know that they are difficult for students. Therefore, if you are unsure of your writing skills, it is best to contact professionals. And in the future, work to improve your writing skills
