Dont do it,
it is going to be way to hard for you
if you also have to study other things, then it becomes almost impossible
but if these units are the only units that you are going to give in the coming may june, and you dont have anything else on your plate
then still it would be beyond the ability of a normal human being
I would strongly advise you not to
trust me I know the pressure....
I looked at M2 and said no way, because sure you can 'finish' it, but then the practice takes a long time man
so please do not do this
it is way to close to impossible.
