This is probably going to sound really dumb, but it's better than making an expensive mistake and regretting it.
Essentially, the module registration page has two sections/blocks, one stating Make any choices from the electives contained within this block while the other is Choose a maximum of n credits from the electives contained within this block.
Since the second block writes a maximum, does this mean that it's possible for me to not choose any modules from it at all? What's the minimum? Also, how will this affect my grades/degree?
