The details about what advance information will be provided in Feb has been published by Edexcel (and applies to Edexcel only)
"The advance information will be given for each paper in each tier, and also collated for each whole tier.
For each exam paper, the advance information will be grouped by broad theme and then topic followed by an appropriate description of the topic. For example: Number: Arithmetic: Order of operations
Advance information will provide a list of topics from the specification that will be assessed on each paper in specification content order, not in question paper order.
Topics not explicitly given in the advance information may still be needed as prerequisite skills to solve questions"
This means you'll know that, say, Venn diagrams are being examined but you won't know if it is the first question on the paper (easy) or last (v difficult).
