Casper Typed Response: How Much to Write in 3.5 Minutes

How much you can write in 3.5 minutes

Each typed scenario gives you 3 minutes 30 seconds for both questions. Once you've read the scenario, that's about 1 minute 30 seconds of writing per answer. There's no time for a leisurely read or polished prose. You need a reliable way to write thoughtful, empathetic answers at speed.

The candidates who struggle most with the time constraint are not necessarily less empathetic or less thoughtful, they simply have not practised producing quality responses at speed. This is a trainable skill, and this article breaks down exactly how to develop it.

How to split your 3.5 minutes

Both questions appear on screen together after you read the scenario. That's an advantage, so use it. Here's a split that works for most people:

How typing speed caps your word count

Your typing speed sets a ceiling on how much you can say. Say you take 15 seconds to read, then type steadily for the rest of the 3.5 minutes. At 40 WPM, that's about 130 words across both answers. At 80 WPM, it's about 260.

These are ceilings, because you also stop to think. So if you type under 60 WPM, lifting your speed is the best return on your prep time. Check yours with our free Casper typing test, then practise for a few minutes a day.

The opening sentence: lead with empathy

Your opening sentence matters most. Raters read a lot of answers and form an impression quickly. An opening that shows real empathy reads as a strong answer from the start. One that jumps straight to problem-solving reads as a weaker one.

The most effective opening sentences acknowledge the emotional reality of the person in the scenario. They do not use the word 'empathy', they demonstrate it through specific, authentic language.

• Strong opening: "This must be incredibly stressful for Sarah, balancing her clinical responsibilities while dealing with a personal crisis is something many doctors face but few feel safe to talk about."
• Weak opening: "I would approach this situation with empathy and professionalism."
• Strong opening: "I can understand why Dr Chen would feel conflicted, being asked to compromise on something you believe is the right thing for a patient is deeply uncomfortable."
• Weak opening: "In this situation, I would first consider the ethical implications and then speak to the relevant parties."

The Acknowledge–Explore–Support structure

Rather than a rigid template (which raters will recognise and penalise), think of your response as having three natural phases. This is not a formula to follow mechanically, it is a way of thinking that ensures you cover what raters value most:

1. Acknowledge: name the emotional reality of the situation. What is the person feeling? Why is this difficult? Normalise their experience where appropriate (1–2 sentences)
2. Explore: show curiosity and nuance. What questions would you ask? What factors would you consider? Hold the complexity rather than jumping to a single right answer (1–3 sentences)
3. Support: offer practical next steps framed collaboratively, not directively. What would you do with the person, not to them? (1–2 sentences)

This structure fits the time you have. At 60 to 80 WPM, that's about 100 to 130 words per answer. Let it guide your thinking without making your answer sound templated. Each scenario needs a different balance of the three.

Common mistakes that cost marks

Having reviewed hundreds of practice responses, these are the patterns that most frequently drag responses from Q4 territory down to Q2–Q3:

• Spending too long on question 1: if the first answer eats most of the clock, the second gets rushed. Each question counts, so two solid answers beat one great answer and one rushed one
• Formulaic openings: 'In this situation, I would...' or 'I would approach this with empathy and professionalism' are red flags for raters who see them dozens of times per session
• Clinical focus: discussing differential diagnoses, treatment plans, or clinical pathways when the question is asking about interpersonal judgement
• Listing without depth: 'I would listen, validate, support, refer' ticks boxes but demonstrates nothing. One well-developed point beats four superficial ones
• Ignoring the second question: some people write a brilliant first answer and run out of time for the second. Your second answer has to stand on its own
• Over-editing: spending 30+ seconds fixing typos and rephrasing. Minor spelling errors do not affect your score. An incomplete thought does

How much should you write per question?

There's no official word count. Your limit is the clock and your typing speed. At 60 WPM you can fit about 100 words per answer, and at 80 WPM about 130. Aim a little under your ceiling, because you need thinking time too.

Quality beats quantity. A focused answer that shows real empathy and clear thinking beats a longer one that stacks buzzwords and lists actions. Treat your word budget as limited, and make every sentence earn its place.

How to practise effectively

The most effective way to improve your typed response performance is deliberate, timed practice with feedback. Here is a structured approach:

1. Benchmark your speed: take our Casper typing test and note your WPM. If it's under 60, add a few minutes of typing practice to each session
2. Start untimed: answer three to five scenarios without a timer. Focus on quality, structure and empathy, then compare with sample answers
3. Add time pressure gradually: try 5 minutes, then 4, then the real 3.5. Notice how your answers change under pressure
4. Use AI feedback: sign up free and our AI will score each answer across the competencies and tell you what was weak
5. Review sample answers: after each attempt, study the sample answers in our question bank. What did they include that yours didn't? How did they open?
6. Track progress: log your feedback each week, and keep a list of the weaknesses you've fixed
