Self Introduction for School Interview

Good morning professors. l'd be happy to meet for an interview. My name is Diana, a senior student in Hebei University. My major is international economics and trade. Among all the subjects l've learned, l love English the best and  l did great job learning it. l have passed CET 4/6, and l also passed the Ministry of Personnel third–level translation examination. l love to read books on the economy, psychology and culture and I like to read newspapers from BBC and CNN during my spare time. So l choose MTI. l am confident and a quick thinker. l always try my best to do a perfect job. If you ask me a question that l don't know, l will tell you that l don't know. But you know what? l will try my best and work very hard to find the answer.That's all, thank you for your attention.

I'm not sure if in your sentence you mean to say choose (present tense) or chose (past tense).
