English graduate students, except MTI, have much more literary language than your agricultural rubbish, and it is useless to learn it. Nowadays, teaching high school students needs graduate students and universities need doctors, which has no advantage over normal students. If you do research, what does literature do?

Try to explore your interest in agriculture. This is the advice for your English major.

Of course, if you are good at English, you can take MTI. If you have the foundation of your agronomy major, your future is still very bright.
