Narrative:

Cleared to maintain 11000. Cleared to turn left to 010 and intercept bos 4R localizer. Student captain got confused and turned right to 110 and started to descend. I caught the descent about the same time ZBW called and advised us to maintain 11000. I took over control of aircraft and got on course and altitude. ZBW did not say anything else.
