Yeah I agree that aspects of the admissions advice on the Cambridge website are rather cryptic and unhelpful, but I bought Pallis's book and it made me less confident and more uncertain about what was actually required- even the title suggests a sort of conspiracy, the REAL rules, the stuff THEY don't want you to know lol. She takes the attitude of a Marxist warrior, and her views reflect the notion that applying to Cambridge entails going to battle against an unfair and biased system, against admission tutors and the people you will be side by side with for 3 years if you do get an offer. She also perpetuates stereotypes about the colleges (I was left with the impression that my chosen college, Peterhouse, was definately either a gay bar or a rugby club). Read the book, it won't not help, but take the advice with a pinch of salt and be aware of who is talking and to whom. At the very least it is certainly socially interesting. Most useful of all is visiting and talking to a Director of Studies, who were all extremely warm and willing to help and advise. Be careful with the rubbish contained in these books and with the often dated perceptions of schools of the whole process.
