Erasing, overwriting, partial marking etc may also be treated as incorrect answer. No deduction of mark will be made for unanswered questions. Possession & use of calculator, logarithm table, mobile phones or any similar electronics equipments are not permitted in the examination. The subjects includes English, Mathematics, Engineering Mechanics, IT and Computer Science, Civil Engineering, Mechanical Engineering, Electrical Engineering and Electronics & Communication Engineering

ENGLISH SYLLABUS :
For English, out of the 10 marks to be awarded, 5 marks will be for questions based on a given passage and remaining 5 marks for basic Grammar and General English of +2 Standard.

SAMPLE QUESTIONS :
Answer questions 1-5 based on the given passage.
About four hundred years ago, many people believed that they lived on stationary earth, which itself is situated at the center of the universe. The world beyond the solar system was a mystery to all. The submicroscopic domain of atoms and molecules was completely unknown. Not even a single law of nature was accurately formulated. The Copernican theory of the solar system (the theory in which the sun occupies the central position) had been published but it had so many objections against it. There was scarcely any activity that could be called as science. Mathematics was just in its infancy.
