Which is correct?
Please read this:
Last week, I started learning Japanese for the first time in my life. Last Thursday, I memorized about half of Hiragana, and yesterday I memorized the rest of the characters and some of Katakana. Originally, I wanted to begin my second foreign language after I reached a high level in English. But I decided to learn Japanese because this year I will probably study it as a liberal art in university. ~~~~
At the last sentence, should I change "in university" to "at the university"? Thanks!
