I agree that it is better for students to study online using computers than to attend class at the university itself. I have two reasons*: convenience and **economics. First, online learning enables the students to study at home without going to the University. Therefore, even the students living in the foreign countries can study with the other students at the same moment. Second, the students do not need to buy the textbooks due to using because they use computers. It is economical for the students. Furthermore, they save the cost of ***going to the University too. Therefore, I think that study online study is good method and will should be expanded all of the world.

*Semicolons (;) basically act like periods (.) and join two similar sentences together. (for example, “I am tired; I want to sleep.” You could put a period here instead, but because the sentences focus on one topic (being tired) you can add a semicolon. Colons (:) are for joining an already complete sentence with a noun (not a complete sentence).

**”economic” must be “economics” because without the “s” “economics” becomes an adjective (a describing word). Since “convenience" is a noun, “economics” must be a noun too.

***You could use the word “traveling” instead of “going” to be more specific 

well written and convincing! great job! :)
