Hey Preeti.

According to the marking scheme of CA CPT, Each question carries 1 mark. You get +1 for each correct answer. There is negative marking of 0.25 for every wrong answer .No marks are awarded or deducted for unattempted questions. Hence if you answer incorrectly 0.25 marks in total will be deducted from your total marks. And 1 mark will not be deducted along with 0.25. Only 0.25 will be deducted.
