CCAT 2012 will be conducted manually (Pen and paper based) at various cities all across India.

CCAT-2012 will be conducted in the form of three objective type test papers labeled as
Section – A (English, Critical Reasoning and Quantitative Aptitude),
Section – B (Programming in C, Data Structures, Data Communications and Networking, OOPs and Operating Systems) and
Section – C (Computer Architecture, Digital Electronics and Microprocessors)

Each section is of one hour duration, having 50 questions of 3 marks each (maximum 150 marks). Depending upon the choice(s) of the programme(s) made by the candidate he/she will have to either appear in just one test paper (Section – A) or two test papers (Section – A and Section – B) or all the three test papers (Section A, B and C).

These test papers have to be answered in a machine-gradable Objective Response Sheet (ORS) by darkening appropriate bubbles using black ball point pen only. Since the ORS will be evaluated by electronic means, it is imperative that the instructions given on the question paper booklet and ORS are carefully read and followed by the candidates. The objective type questions in all the test papers will have four choices as possible answers, of which, only one will be correct. There will be +3 (plus three) marks for correct answers and negative marking for wrong answers in all the test papers. For wrong answer to an objective type question, candidates will get -1 (negative one) of mark. Multiple answers to a question will be treated as a wrong answer. For each un-attempted question, you will be awarded 0 (zero) marks.
