Multiple choice quiz graying out incorrect answers until correct chosen

[David Nicholson]

Hey Ben,

Thanks for your response.  I eventually got it and opted for having
the participant choose a,b,c,d then press enter.  This way there was
not an accidental choice and they could think about it before they
answer.  I did it a very similar way as you described.  I did end up
using a single slide with four separate text boxes for a,b,c,d and one
for the question of course.  I then compared their answer using instr
and if the accuracy was 0, i used if then statements to grey out the
incorrect and just go to the beginning of the slide.  This would
repeat until correct.  I then cleared the slide of incorrect and
picked another question by random.  I implemented a counter to keep
score of correct and deductions, then terminated the question list
once a minimum score was reached.  My next step it to export this
score along with subject number and session to use in the next test as
a base score.  I'm pretty sure I have a good idea how to write that
up.  I'm also looking into a way to take the data from multiple
sources and automate it giving an overall score comparison.  I know e-
kick no longer works but I just need to devote more time to get the
coding right for this.  I was also thinking I may have to end up using
a CSV but I would rather not as that seems like it would take too much
time.  If you have any ideas feel free to make suggestions.

Thanks,
David
