An AI score feels like a verdict. It arrives instantly, it has a number on it, and it looks objective. That is exactly why it is risky.

What many prep sites actually do

A common setup is simple: take a general-purpose AI model, connect it to the back of a website, and instruct it to mark students. The student types an answer and gets a score. There is usually no published evidence that the score matches how real CASPer raters mark, and no proof that it predicts anything. The number comes out of nowhere.

Arvin Ardakani has seen what happens next. Students trust the score, expect the same on test day, and come back with a 2nd-quartile result, or an interview that did not go their way.

Why a generic model gets it wrong

AI works from patterns. It is good at recognising an answer that is organised and uses the right words. It is much weaker at judging whether the reasoning underneath is deep, whether the perspective is fair, and whether the answer would leave a real impression on a person. It also tends to tell you what you want to hear. Arvin regularly has to correct things AI says about an answer, and he is open with students about where it can and cannot be relied on.

Humans mark CASPer, and humans offer the place

CASPer responses are scored by human raters. Interviews are run by people. The decision to accept you is made by people. That is why preparation has to be judged by a human who knows what those people respond to. Even a student who memorizes every AI-written answer will not do well, because the raters are listening for a person thinking, not a script.

How to use AI without being misled

AI is powerful when it is trained properly. Arvin Ardakani trained his own model on how he teaches and corrects his students, so his students can practise and get written feedback at any hour. But the diagnosis of what is holding a student back, and the strategy to fix it, come from him. The right coach balances both: AI for constant practice, a human for judgment.
