Dear aspirant

It would be better if you make clear which ASAT you are talking about.

But if you are talking for Allen ASAT then it's not cleared about minimum marks .

So it is going depend only the total on level of question asked

If you Scored around 200 marks then you you got approximately 25% and if you got 232-240 marks then you have chance to get 50%

I hope it will help you

thank you
