I just took the 55. Was expecting to fail it the first time, just wanted to get a feel for how hard it was.
Read the material, took the exams. (4 hrs)

When I hit the finish key, thought I was going to get a 50. Ended up passing with a 76.
Guy next to me studied less than me and got a 74.
If you can quickly "understand" the material rather than just memorizing everything real quick, IMO the 55 is not that hard.
Took the 7 very lightly and put in less than 15 hrs and failed with a 68. Then I took the class from STC put in a couple more hours and passed.
If you study, you will pass. Amount of time it takes....just depends on your level of test taking ability.
