Which Exam centre is the most convenient for West London?

Hi,

Anybody from West London, please advise which centre is the most convenient to travel from West London.

I use public transport and it takes almost 2 hours to get both to ExCel, and to Alexandra Palace or London-Chessington.
Location of London-South East is not disclosed until ACCA know the number of students registered for this exam centre.

For the past 2 years I always took exams in ExCel and was wondring why there is no centre for West London.

Thanks for advice in advance.
