Hi there, I just completed all of the IFR courses and finished reading Ron's ground lessons, i'm now ready to pass the IFR checkride.

Now, I tune SEA VOR (116.8) and maintain a heading of 340°, descent like it is mentioned on the Tacoma intl chart until i reach the Missed Approch point (M) at about 1500'. The intructor then tells me to execute the missed approach procedure, i start to climb maintaining my heading to 340.
Now the problem is the next task i have to do
The instructor asks me to turn left heading 160°(not sure about this one) and maintain 3000'
I do so, but the checkride quits and it says i failed.

Am I wrong with the 160° heading or is it something else?

Any help is welcome.
Thanks!
