Practice exams for 70-480

KarolW

I wonder which practice exam I should choose for the 70-480 exam. Microsoft's website gives links to three choices:

- Selftest (108 questions, 180 flash cards)
- Measure Up (120 questions)
- Transcender (120 questions, 200 flash cards)

Which one would you recommend as the most effective for passing the exam (or other not mentioned here)? Also, I'm a bit surprised with number of questions on these tests. JS, HTML5 and CSS3 are quite vast topics, 108-120 questions seems to be a bit low number.
