121 sounds reasonable if you guessed the last six ones. What the test measures is essentially how many questions you get right before you start guessing, whether out of boredom or because you don't have enough time to figure the questions out (the test cannot really differentiate between those two). For reference, I scored 133 and had to guess the last three or four ones; this is consistent with the last time I did a test like this several years ago.
