It makes sense. GRE has 3 sections. The quantitative part is very easy, but the other 2 are complicated for me. That is the reason that I will need to spend some time preparing for GRE.
My idea is get in a Masters. If I really enjoy the masters, then I will try to get in PhD. Also, if I will try to get in PhD, my idea is to apply to great American universities. But, I'll only apply if I believe that I have chance.
My question here is not about Masters (I'll get in the Masters), my question is if good American Universities will reject (or will be more hard to get in great American Universities) due to my age and my previous PhD.
