Exam insights

Counted from 5 past EC-602 papers.

Marks asked per paper, by unit

  • Unit 1 Radiation 21 marks
  • Unit 2 Antenna Fundamentals 32 marks
  • Unit 3 Types of antennas 20 marks
  • Unit 4 Aperture and slot 15 marks
  • Unit 5 Propagation of radio waves 24 marks

Average marks of the questions from each unit in one paper. You answer only some of them, so the total is more than the paper’s maximum.

Asked again and again
