The reality is too late for a 34 y/o graduated to get hired for a fresh grad job and compete with 23 y/o...even if yes you get hired the salary surely can’t be high. Can you accept 2k salary? it might be cruel to tell you this but I think it is important as well to tell you as a pre-alert
In my opinion, your ultimate purpose is to earn money, so don’t go to campus spend five figures or six figures to get a certificate, while the outcome high chance will look bad when you graduate.
Just to remember you have family to raise ...
