Course name: Introduction to Programming in C
Dates of exam: 30 November 2014 (or) 14 December 2014 (choose any one date)
Exam Session time: 10am - 1pm
Examination centres: The exam is to be conducted in 100 cities across India whose list is available on the registration form.
Registration fees: Rs 1250/-
Mode of payment: Only online payment - debit card/credit card/net banking

 The hall ticket will be available for download from 24 November 12 noon onwards.
The eligibility criteria for obtaining the certificate is the following:
A = average (out of 100) of the 3 highest weekly online assignment scores
B = score (out of 100) from proctored exam
Combined score = 0.5*A + 0.5*B
Only those whose combined score is above 60% will get a certificate. 

The certificate will carry the combined score and also a link to the NPTEL website, where on logging in, your week-wise assignment scores and your score in the proctored certification exam will be displayed. 
So, those of you who qualify will need to regularly submit assignments to get a good combined score. We expect the certification exam to be fairly competitive given the large number of good students in this course.
The Course:

This is a course in programming in C. No prior programming experience is assumed; however, mathematical maturity at the level of a second year science or engineering undergraduate is assumed.
We emphasize solving problems using the language, and introduce standard programming techniques like alternation, iteration and recursion. We will briefly glimpse the basics of software engineering practices like modularization, commenting, and naming conventions which help in collaborating and programming in teams.
Given a problem, we pay attention to the following questions:
  1. What is an algorithmic solution to the problem?
  2. How do we translate the algorithm into C code?
  3. How efficient is the code?
  4. How maintainable is the code?
It is expected that by the end of the course, students will be comfortable in :-
  1. Attempting algorithmic solutions to problems
  2. Designing and coding moderate sized programs running to the order of a few hundred lines of code, and
  3. Reading, understanding and modifying code written by others.
