Undergraduate / plan to do in next six months [2]

I would like to (register, enroll, and license) a Toeic class next six months, and I think it is essential for me. Many reasons are being it learning. Firstly, as a freshman English-majored student, I will spend 4 years following up on my major. I'm going to graduate as long as I have an English certification. Next, now that English is an international language, society requires us to know several languages to facilitate communication, attend conferences, or even study abroad. Therefore, I can easily personality development, make plenty of friends, and widen my utility knowledge. Last but not least, through learning English, my brain will be exercised and increase my cognitive flexibility. To sum up, enrolling in the course is my best decision.
