thanks - I wasn't sure if it would be overexposure or underexposer

I'd say overexposure was more likely - if the aperture hasn't fully
stopped down before the shutter fires, it will let more light through than
you wanted.

Put the lens on a body, point it at a light coloured wall or somesuch,
open the back and watch what happens when you fire the shutter at 1/60s or
slower.  You should be able to see if the aperture closes all the way.
Compare it with the same trick but with the shutter on "B", when ,
presumably the aperture will certainly have had time to close to the stop
you've set.
