those tests clep spanish and french are not hard, they are tricky, I took both of them and scored a 79 and 80 and got 24 credits in just one saturday , they go very fast and for all the audio part it doesnt allow you to replay, they give you 4, 5 sentances consecutively without any possiblity to replay(more like a cheap memory test combined with the difficulty to understand a foreign language) and then ask you some shabby tricky questions, so my suggestion for you is that next time before you start the test, ask them to provide you pen and paper(if they ask why say I need to write the sentence to check the structure to see if it looks right ) and try to take super quick notes while you listen, that should get you to 66 without any problem if you have a decent spanish level. again hard vs tricky not the same, these tests are tricky so watchout !!
good luck !
