    4u cambridge questions are too hard

    Also I thought I'd also mention in response to 'other textbooks' I did mention Steve Howard before, which is freely available online.

    4u cambridge questions are too hard

    Look everyone's going to have a different opinion on this but here's my two cents: The Cambridge Textbook is designed to have an incredibly wide range of questions - from the most basic to the hardest. The intention is to be able to cater for students at different levels. The HSC is designed...

    A trial question

    Ahh okay, thank you Would you not expect the actual chemical composition of the stars to be different? Like presumably a main sequence star still has hydrogen while a red supergiant does not, so you'd expect the lines to not just change in thickness but in position as well? What have I...

    A trial question

    Mathematics Extension 1 Predictions/Thoughts

    Idk everyone’s going to say something different. Every day it seems like I feel differently on it. I think it’s undeniable multiple choice was harder last year, but Q11,12 do seem to be harder this year. Q13 I thought was really easy this year and Q14 I’m unsure about - 2022 was way longer (in...
