I am an electrical engineer and I did the exam yesterday and most of the questions were really tough and you need to be prepared before taking the exam.It is not straightforward exam.
Things to remembers :
1- If you fail the exam,don't panic , you still have another chance.
2- There are about 27 questions and the pass mark is 13 at least out of 27.
3- Study all your college subjects and get ready for challenge.
