Regarding the test, what did you mean by "only answer in extremes."
Also do you have previous work experience? Is that a make or break concern?
Let me expand on Peco's example to make it a little clearer. A question on the test would look like this:
How dependable would you say you are?
1. Very Dependable
2. Dependable
3. Undependable
4. Very Undependable
In this case it is obvious you want to choose answer #1. The "hard" part is when they ask somewhat ambiguous questions like:
"You like to take frequent breaks when you are faced with challenges. Agree or disagree?"
1. Strongly Agree
2. Agree
3. Disagree
4. Strongly Disagree
In this case, your answer would change depending on your interpretation of the question. On the one hand, agreeing may indicate that you have trouble coping with stress. On the other hand, disagreeing may indicate that you have trouble recognizing your limits and knowing when you need to take a break. What you need to understand is that the question was intentionally designed to be ambiguous. In these kinds of tests there are two types of questions. The first is like Peco's where they care WHAT your answer is. The second is like mine where they care HOW you answer. Each of the answers to each question has a point value. They work as follows:
Type 1
1. +1
2. 0
3. 0
4. -1
Type 2
1. +1
2. 0
3. 0
4. +1
At the end of the test your score is added up. If your total score is higher than the minimum score Disney has chosen as the pass/fail mark, you pass. Obviously, the higher your score the better. 2 and 3 answers in both types are worth 0 points which means those answers won't lower your score but they wont raise it either. In type 2 questions, 1 and 4 answers are +1 regardless so it is a win win and only goes to raise your score. In type 1 questions, 1 answers give you +1 and 4 answers give you -1. This means that if you don't even read the question and blindly answer it with one of the extreme answers, you have a 50/50 chance of getting the "right" answer in a type 1 question and a 100% chance of getting the "right" answer in a type 2 question. All of that to say that by answering the questions in extremes, you theoretically reduce your chances of picking a "bad" answer to 1 in 4. In reality, the chances of picking a "bad" answer are even lower than that because you can generally determine whether you are answering a type 1 or type 2 question by how obvious or ambiguous the question is and adjust your answering strategy accordingly.
Also, for your second question. I personally have had two jobs and a lot of volunteer experience, but I have seen plenty of people on these boards who got in and have had zero experience of any kind. Even more than the CP, the CS program is specifically geared towards people with little to no experience.
Hope all that makes sense and helps.
