! and for Q7iii) when are we supposed to use the "> or equal to " and ">" ? .... :( !!! THANKS

When the image for f= -6 is real, or exists. Use equal to sign then. Depends on the question also.

When you use > sign, the image will exist just above this value, but not for the value itself.

Find the stationery point first, if it lies between 0 - 5 seconds, you must do a two-part integration, taking the 0 - stationery point and stationery point - 5 as the limits in the two integrals ... Gee I am currently at school and will be having my examination in an hour :(

Paper 1 went well :D An A is assured as the grade threshold for Paper 1 is relatively lower when compared to Paper 2 ...

Not neccesarily Darren.

The paper was easy. The threshold would probably be 69-71/80 for an A. It has happened before in the Oct Nov Paper 2009 which I found considerably more difficult.

O/N 09 is pretty easy ... My score would probably be in the 75 + range, allowing room for careless mistakes. I have paid additional care in ensuring that I have all the steps shown so I would still get a follow through mark as I won't get penalised twice for the same thing. There are some questions that I find tricky in today's paper, I will discuss them tomorrow.

A* in IGCSE Additional Mathematics is an unrealistic goal. A friend of mine got 10 A* 1 A last year, the A grade that she attained was in Additional Mathematics :o

Hey I'm aiming for A* for IGCSE Add Maths :D I scored A* with 98% for my mock exams, so I will try my best to keep that A* for the real exams as well.

By the way, my paper 1 went quite well :D

Oh thats great, always aim high.. :)

Yea i too got A*s in my mocks...but CIE's A* is no where close to the school's A*.

Its a huge ratio of students appearing for that exam..

Last session, i was sure i wud get 75+, resulting in the excitement to receive an A* in arguable IGCSE's most difficult subject.

I got an A :-/

Well do you know what is the normal range for A* (estimate)? Since for the mock, the grade boundaries at my school was >85% for an A and >90% for A*, which I assume to be pretty high. Don't tell me CIE'S A* for Add Maths is >95% lolz :P

Sometimes, YES, when the paper is simple. Too simple for Cambridge standards.  ;)
