This text is for the following question!
 

I'm going to finish my English classes in three semesters. I'm taking a grammar class this summer. I registered for it last week. I'm taking only one class this summer. In the fall, I'm going to take reading and conversation classes. I'm also going to take another grammar class. Three classes will be a lot of work, so I am not going to work full-time. That will give me time for my homework at night. I'm also going to save all my money this summer. That will help. There will be an online writing class in the spring. I hope to take that class. It will be my first online class. I will also need to take one more reading class. That will be my last English class.

What is the writer going to take online in the spring?
