Slow in parsing and digesting Math word problems at case interviews - how to improve?

Hi

I am new to management consultancy and business problems, although I do have a background in Math.
I am slow in parsing/understanding Math word problems at case interviews. I think this is because:

1. Taking notes as the interviewer reads out the case, rather than having info in front of me
2. Lack of familiarity with business terminology

Are there any resources/books that I can use to practice such problems, so that I start feeling comfortable with them, and thus have my mind over matter rather than being anxious that I may have left out some info during note-taking.

Thanks a lot
