Hi Friends

I m Niraj Kumar Ranjan from SCSVMV University, Kancheepuram. TCS came oncampus in my college on 17th & 18th July 2008. On 17th it coducted online test in which 13 students cleared the test out of 175. On 18th it conducted HR and MR interview. At 4'O Clock evening final result came and my name was shortlisted among with other 5 students.  


Verbal Section.
Quantitative Aptitude.
Critical Reasoning.

Verbal Section (32 questions in 20 min):
10 Synonyms
10 Antonyms
6 Sentence Completion
6 RC

For Synonyms practice all Word List exercises of GRE BARRON-12th Edition with heading Synonyms. No need to mugup the meaning of all words. You just keep the true option of respective word in mind because the words with options are just copied in question paper. So if you have previously seen a particular word then u can resemble it in exam and can choose correct option.

For Antonyms practice all Word List exercises and Model Test Paper(given back side of GRE Barron-12th Edition) of GRE Barron-12th. If you practice only Model Test Paper's Antonyms then you can answer 6 ques out of 10 during test.

NOTE: you skip words with heading “Synonyms and Antonyms” given in Word List exercises. Sentence Completion are also from GRE Barron but it in the form of a paragraph with combination of 5 or 6 sentences. If u have time, practice it otherwise skip it.

RC is from GRE Barron-12th. Practice all Model Test Paper's RC if you have time.

Quantitative Aptitude (38 ques in 40 min):
Note: For this section there is no need to solve any book you just solve as many questions of previous years as possible. All ques are either repeated or data is changed. Therefore you must know the methods to solve those questions, it will help you if you forget the mugup answer or if data is changed.

Assuming no error during transmission, write a formula to calculate the time taken in seconds to successfully complete the transfer of a file of size N kilobytes.
