When the gyro reading is higher than the true
Similarly there is LOW .
For example if ship is heading 000 degree true North and gyro is showing
a) 358 degree (this value is less
b) 5 degree true (This value is higher than the
Compass error is the angle at the magnetic compass contained between the true north and compass north.
CE is named EAST if the compass North lies to the right of true north.
CE is named WEST if the compass North lies to the left of the true north.
Error EAST compass LEAST
Error WEST compass BEST
Question 1 .
If the bearing is 330 Degree true & compass error is 10 Degree West. Find the compass bearing.

According to the above rule , since error is West compass will be Best so error is added to true Bearing to get the answer.
Or you can use CADET rule .
