This will seem wayyyyy of topic but early on in the thread some guy was saying weigh up the options for post grad entry. Was he referring to the BM6, as I thought it was undergraduate but just an additional year 0 at the start.
You cannot apply for BM6 post-grad. He must have been talking about BM4 which is different.
Go here and apply. Shouldn't take too long for someone to respond to you. You'll get a mentor and then be welcome in the PS Helper's Tea Room and other private threads of awesomeness
