practice book worked solutions maths a level

What exam board are you doing? Edexcel has worked solutions on their online book and they're also available on PMT

edexcel and i already looked and i think they only have them for the textbook and not the practice book T_T. I was hoping i could find solutions somewhere else

yeah unfortunately they dont have worked solutions unless someone has answered specific questions and released them online although I doubt you'll find it for all the question. Their main aim with practice books is so you don't rely too heavily on worked examples and have you retry methods to get the final answer
