Ok, i'll do my best to come up with the answer. Do you remember "CDMVT"?
This is always the method i used and got tought: -
ALWAYS DRAW IT OUT SO U CAN SEE WHATS HAPPENING: -
←Add if East →Subtract if East
←Subtract if West → Add if West
Compass Head…Deviation……Magnetic Head……Variation…..True Head
030 3W 033 8E 025
Magnetic Heading 030+3 = 033
True Heading 033-8 = 025
So from what i can see it's answer B 025 degress's. Is this the right answer?
Hope this helps
