The BA vectors test uses higher components than the cockpit web test eg NE 35 etc whereas I think cockpit web only goes up to 15. The difficulty I had was having practiced the cockpit web tests using a mouse to position the airfield, I found it harder to be as accurate when using the joystick. I find it works better by going for the diagonal coordinates first NE/NW etc, then the simple N/E/S/W coordinates second as the diagonals are harder to get accurate. On average I was getting 2 more right on the cockpit web test than I did in BA.
