Surprised by services in the first 2 practice exams

[Sarah-Jones]

Hi there, I have done Stephane Mareek’s course and his practice exams and averaged about 70% on those. I have done 2 exams here today and I’ve scored in the 50s for both. Both of the TD exams had so many questions on x-ray, kinesis and ECS which are services I have not done a lot of study on as I have been told by so many people they won’t feature much on the exam so I am confused why so many questions covered these services? Any thoughts would be most welcomed. Thanks
