I have tried all the scordo tests and was able to find first 10 tests Easy.

However have found Tests 14 to 18 extremely difficult. I was able to score just 70 percent or little about 70 percent in these. Also was right in time and sometimes took more time. Each 50 Question test took a whole lot of energy from me. My exam is very soon and am concerned that am getting low scores and do not have time now to do more reading

I found tests 16-18 most difficult

Are most of the real questions on  exam lengthier or dfficult than Scordo tests 14-18?
