my opinion is............. I massively disagree with the cost of these OA courses, but I think their book "tell me about a banana" was really useful, and helped me a great deal putting together the first draft of my personal statement. My mum also got a letter sent to her saying "OMG 58% SUCCESS, SEND YOUR KID ON THIS. ONLY £850"
I'm 21, luckily knowing the value of £850, and would never in a million years spend it on a company that tried to pretty much, scare my mum lol Plus my car needs servicing, i need to by some more books bla bla bla. basically i fail to see its worth.
Niccolo - you seem very close minded for a oxbridge undergrad/applicant. I can understand you have your own opinion on this, but realise that you might be wrong. And no one apart from the admissions tutors can rate what chance anyone has.
Akademic - mate, you don't seem very articulate for an oxbridge applicant. There are far better ways to show your frustration with peoples views than typing swear words that are just star'ed out anyway. Not that i care really haha, you can argue with each other all you want.
And finally, TSR is a massive resource for anything academic. The amount of help you can find on this forum is unbelievable. and people do know what they're talkin about. That includes applying to oxford or cambridge.
