The Subject of Electromagnetics
Studying EM: Survival Guide
• The course is MATHEMATICALLY INTENSIVE.
– Attend the lectures and the tutorials. Most of the examples
solved in the lectures are NOT included in the posted notes.
– WORK AT HOME AFTER EVERY CLASS
• Review the slides from the Lecture.
• Read the respective chapters/sections and their examples in
the textbook.
• Solve homework. Do not miss homework as it adds up quickly.
Final exam takes problems mostly from the homework.
• Seek help: (i) from the Professor, office hours Tuesday 2pm to
5pm; (ii) individual appointments possible (email ahead of
time); (iii) from the TAs
Studying EM: Survival Guide
• Work out all examples/problems
recommended before midterms and final
exams. PRACTICE IS CRUCIAL!
• YOU CAN NOT REMEMBER ALL FORMULAS.
Remember only definitions and fundamental
physical laws. Try to grasp the physics behind
a formula or a solution. You will have 1 crib
sheet allowed at the midterm and the final
exams.
Exam Formats
• Exams are closed-book.
• HOWEVER, crib-sheet is allowed - 1 page (1
sheet, Letter size, both sides allowed) of your
own writing.
• Cheating results in 0 grade and academic
dishonesty charges.
• Quizzes: randomly given during lectures
