This is a Polar Stereographic chart with a Grid overlay - the grid is shown by the straight 'shaded' lines .... now look at the 0 degree meridian - you will see that the Grid is actually aligned to this - hence the relationship between GRID track and TRUE track is straight forward, and is given to you by the formula given bottom right of the chart:

GRID = TRUE (+ WEST LONGITUDE or - EAST LONGITUDE)

Now, this is actually not really relevant to this question ..... TRACKS on this chart are MAGNETIC if there is nothing after it (so the 353 out of VIGRA is 353M), TRUE if there is a T after it, or GRID it there is a G.

Lastly, with this grid overlay, if you drae a straight line on this chart - then you can see that your GRID track will not change - initial GRID track will be the same as final GRID track.

So, what is the Grid track out of VIGRA?? GRID doesn't change .... so simply follow PTS P .... eventually it tells you 344G .... keep following it .... it says 344G

If you want to measure it with your protractor, you can ...

If you want to use the formula, you can ... 353 M, variation at VIGRA 3W, so 350T, therefore ... GRID = 350 - 6E = 344G

This is a regular Exam question!
