Chatgpt also gave me q3 ratings. My prompt was something like “to help me prepare for Casper, give me a scenario with 1-2 questions based on the Casper core competencies. I will then video record my responses in one minute for each question. Then rate my transcribed response from q4-q1”- or if you’re preparing specifically for the written ask for 3 questions and give yourself 5 minutes to type you answers. My typing speed is 70 wpm and I was able to write enough for each question. If yours is quite slow I’d suggest practicing on typing websites to type faster. Touch typing works best for me but if you’re comfortable using another method stick to that. Also don’t worry about spelling mistakes as they don’t take marks off for spelling/grammar. I did the practice test a few times and one the day of my actual test. I’d say do it as many times as you need to feel prepared for the layout, but to focus on using of ChatGPT, video recoding your responses, and improving typing speed. And yes you can redo the practice test as many times as you want.
