which one is better?

[asad hussain]

Which one is better? I have to use each of these lines under the heading of "Tutor" in my resume. I just want to tell them what I do.

A. Teach Secondary and ‘O’ level students all of their respective subjects.

B. Teach all subjects to Secondary and ‘O’ level students.

I would prefer the second version. And, depending on who you have to send your resume to, I might even quickly sum up the different subjects in brackets if not known to the addressee.
