Accounting standards

Hi everyone!

I am struggling with understanding the IASs and IFRSs necessary for this exam (I am using the BPP text book), but it seems that I am unable to resolv any past question from section B. Do you think is worth to start reading all the standards required by the exams? Or what approach should I use in order to be able to resolv some tests if the theoretical knowledge is so poor? I will appreciate any other material that you can recommend me.

Thank you for your help!
