Admission Procedure

Admission Procedure for PhD and MS(R) Admissions November 2017


General Instructions:

·         All shortlisted candidates must report at the CS department office at 9:00am on 11 Nov 2017.

·         Note that the presence of candidates undergoing the interview process (i.e., those who qualify the written test conducted at IIT Ropar) is required on both November 11 and November 12, 2017.


Test Scheme:

·         Selection process consists of a written test (consisting of multiple choice questions), followed by one or more round of interviews. Candidates would be screened after written test and after each round of interviews.  The interview process may involve written as well as oral component.

·         Written test would be for 90 mins. The test would consist of following two sections: (a) Core Computer Science and (b) Advanced Computer Science.

·         Section on core computer science would cover topics from Discrete Mathematics, Algorithms, Programming and Data Structures.

·         For the section on Advanced Computer Science, the students would be given an option to choose one topic from the following 6 topics: (1) Digital Logic and Architecture, (2) Basic Probability and Linear Algebra, (3) Computer Networks and Operating Systems, (4) Databases and Software Engineering, (5) Digital Image Processing and Vision, (6) Machine Learning and Artificial Intelligence.
