one last chance

Not only is this your duty as a father but it will give you a much needed self esteem boost to take charge of this situation.
Not talking down to you man, I've done similar to yourself!

Have a sit down with the son and talk. His grades are important and he doesn't need the hassle of resitting exams later in life because of his Ma's behaviour.
Sounds like he needs some reassurance.

I would take a copy of these grades and show your wife that her behaviour isn't just affecting you.
This is not to make her feel guilty. This is to make her realise that her actions affect others beyond you.

I realy resent this "put yourself first" culture we have become. Sometimes, we DO have to think of how our actions affect others.
Children especially.

This is an opportunity to reclaim some of your masculine appearance. Women today are seeing us as weak and disposable. Because we let them overstep boundaries all the time
