Hi professor,
My name is Jianning KANG and I am currently a third-year student majoring in bioinformatics. I am now preparing for the TOEFL this week. I have tried to upload the passage to Grammarly to edit the grammar mistakes. But I am not sure how the quality of the overall structure and sentences. I would highly appreciate it if you would like to have a look on my article.
Best,
Jianning
