Sample Questions for IIA Entrance Exam
The syllabus for the IIA entrance exam is the standard BSc. & M.Sc Physics syllabus covering di erent areas of specialization. In particular, it presumes that the candidates have taken basic courses in Mathematical Physics, Classical Mechanics, Electromagnetic Theory, Quantum Mechanics, and Statistical Mechanics.There will be some questions in special subjects such as Condensed Matter Physics, Nuclear Physics etc in addition to coverage in applied areas such as Electronics, Instrumentation and Optics. The question paper will be multiple-choice. It will contain questions of two levels of dificulty. The rst level will have 30 \easier” questions carrying 1 mark each. The second level will have 30 \dificult” questions carrying 3 marks each.
