Test Pattern

IAT is conducted as a computer based test in the centers across India. IAT consists of 60 questions: 15 questions each from Biology, Chemistry, Mathematics, and Physics. Total time for answering the test is 3 hours. Questions are of multiple choice type with only one correct answer. * Each correct answer is awarded 4 marks. * Each incorrect answer leads to the deduction of 1 mark. * Unanswered questions are awarded 0 mark. * Therefore, maximum marks awarded in IAT are 240. The total marks obtained by a candidate out of 240 is considered for preparing the Rank List. Not every candidate appearing in IAT is awarded a rank. Rank cut-off is announced at an appropriate time. Further, getting a rank does not guarantee offer/admission to an IISER.
