London - Excel center

Anybody know if public transport to Excel center London is reliable? I am taking my test in London first time and am not sure if the DLR is reliable … Thanks,

DLR is reliable but it’s really jammed on the exame day but it should not be a prob. See you there.

thanks- good luck !!! Also are taxis realiable in London?

yes, but expensive. Also note that the Jubilee line is not in service that day.
