Hello,

Is it possible for a student to see a log listing all of the questions he answered wrong? Can I set this through actions? If so would you be so kind as to let me know how?[;)]

Several ways.
One is to make a global variable per question, set it true or false depending on the students answer. Then on the end look for eacht value.

Another way is to make a string and add the number (or any other property) to this string. In the end, copy the string to a textfield.

I'd probably add a variable per question as Barend has suggested. Then at the end of the question block have a page that shows a 'table' of results. This would be fairly easy to do.
Uisng this approach raises the possibility of having some conditional feedback attached to this page which would be more of a pain to set up but look rather cool.
