I assume these questions are never going to be used in my life ever again and yet here I am testing myself.

can we talk abt threshold frequency for the first question

[@PhysicsHQ]

Hi. Sure thing, go for it.

[@suhanisood6407]

which exam borad are these questions for

[@PhysicsHQ]

I collated these for OCR but they should be applicable for AQA and Edexcel
