ü Errors
and uncertainties:(V.V.V.
Imp topic)
Try to clear the concept to find absolute and percentage
uncertainties.
Then, read the book lines and practice the MCQs.

and percentage uncertainties:
Must clear concept about precision and accuracy. Clear
concepts regarding fractional and percentage uncertainties. Practice numerical
questions.
Read Article 1.6
ü Assessment of total uncertainties: (Most high yield topic.
Numerically very important)
Read topic 1.7 clearly.
Memorize the methods for finding the uncertainties in
addition, subtraction, multiplication and division.
Pay special attention to power factor. Average value
uncertainty measurements and timing experiments uncertainties.Practice MCQs as
much as you can.
