What courses are you going to take next year?
Well, I am certainly going to take chemistry and physics, but I haven't decided on the other subjects yet. I'd like to take English.
Why are you going to take English with chemistry and physics?
Because I want to study English literature. But I think chemistry is better for getting a job.
Of course it depends on what you are going to do when you leave college. Have you decide what you are going to do when you graduated?
I am going to be a, well, I hope to be a research chemist.
