[@mariahussain7360]

Your videos are so helpful. I have a question, why did you multiply 25 with 8.5 for the maximum possibility whereas we know that length's upper bound is less than 24 and widths upper bound is less than 8.5? Please help!

[@1stClassMaths]

The upper bound is 8.5.
An upper bound necessarily a number we can achieve it is just the boundary. We can have any number up to 8.5 so we consider 8.5 the upper bound.

Note which symbols are used. In lower

Why r there missing topics on the checklist for edexcel higher on your website like pythagoras

[@1stClassMaths]

I haven’t made videos on all of the topics yet?

@@j0sh.f2 Am trying as fast as I can. Each video and booklet with it takes probably 8-10 hours for reference!
