PRINCE2 Open Exam booking workaround

Attempting to formalise my PRINCE2 knowledge has been frustrated by the fact that the Open Examinations in the UK conducted by APM Group are booked through a web site booking form which which uses some outdated JavaScript to display available booking slots. From my testing this appears to only work on Internet Explorer on a PC, though Internet Explorer on the Mac will display the options even if you can't book them!

I'll see if I can persuade them to fix this, but in the meantime, if you are a user of Firefox or Safari you can circumvent their JavaScript museum by typing the following line (as one long line) into the location bar and hitting Return:

javascript:var str=document.f.T1.value; document.getElementById("Topic").innerHTML=str; document.getElementById("Topic").style.visibility = "visible"; alert("Done!");

Replace "T1" (for Milton Keynes) in the above with "T2" for Winsford or "T3" for York.

Once the dates are displayed you can proceed as normal.
