Have you tried the Lime Grove campus of Hammersmith and West London or even Paddington collee fella? I know of both these colleges but not sure if they would do 2391. BTW as far as I am aware, the 2391 has been split into 2 courses (2392-10 and 2392-20)
The plan was to split the 2391 into 2392-10 & 2392-20. But because the 2391 is such a well known qualification number, both UK and Worldwide. The C&G has decided to keep the 2391 as it is and to just add a smaller (apparently easier) 2392-10 too.
