Can you also see examination style Questions?

It would be enormously time consuming to also answer all the “Examination Style Questions” so I’m limiting coverage only to the regular “Problems”, of which there are still more than 9500. If you need help with a “Text book general problems”, my suggestion would be to try and find a regular “Problem” that is similar to the “General Problem”, and see if you can apply the same problem-solving technique.
