*I think* you are allowed them in P4,P5,P6. I would like some confirmation.
3. for P4, P5 and P6, at least for Edexcel, you are NOT allowed graphic calculators nor ones that do integration or differentiation or any algebra, etc.

That isn't right. For Edexcel P4-6 you are allowed any calculator (including graphical calculators) except those which will do *symbolic* calculus (ie. if you ask it to integrate x wrt. x, it will say 1/2 x^2 instead of telling you the answer is 1.2469453135 between two limits that you put in). This means you can use calculators such as those in the casio 9700 series.

Graphic calculators make lots of things a lot easier in P4 and 6 especially. They make polar co-ordinate questions easier and make lots of matrix questions easier, (and easy to check), although this is why when asked to find an inverse 3x3, they throw in a k or an x for one of the values.

Here is the edexcel rules that are on the front of the papers (I took this off an old P6. The same is on P4-6. You are limited to a standard scientific calculator in P1 and P3 and I can't remember about P2)

(Original post by EDEXCEL)
Candidates may use any calculator EXCEPT those with the facility for
symbolic algebra, differentiation and/or integration. Thus candidates may
NOT use calculators such as the Texas Instruments TI 89, TI 92, Casio CFX
9970G, Hewlett Packard HP 48G.
