The course was alright, but the final test was so frustrating, not because it was hard but because it was unfair. I answered a question in one way and it said that answer was correct (but i didn't have enough points to pass the test). So when i tried again, i answered in the same way and now my answer was "incorrect". And it wasn't one question either, for me it was question 2, 8 and 9. The answer that i chose for question 9 was correct the first time, then the second time the same pick was considered incorrect and the third time the same answer was correct this time. It's very frustrating that the answers are sometimes considered correct and sometimes the same ones are incorrect in their book. And i have to wait 48 hours to try again. I can admit that the first time I answered some questions incorrectly and that i didn't deserve to pass, but on the second attempt, two of my answers which were previously correct, were now counted as a mistake. And on the third attempt i had 70%, so just one question away from passing and it was the same thing. Please fix this.
