Questions

No. It is a cheatsheet of the important points, formulas and facts. Keep it on your phone and use it all through your preparation: before a mock, when a topic slips, and for one full read in the final days.
How do I get it after paying?
It's yours the moment the payment clears, and you come straight back to this page with Download and Read buttons. It stays in your ProSyllabus account.
