Where to find good pharmacy (Mpharm) year 1 Calculations practice question?

Hi, I have just started my Mpharm course this academic year, and I have briefly started learning about basic calculations such as % concentrations, molar concentrations, c1v1 = c2v2, dilution factors, ratio parts. They get a bit confusing sometimes and wanted to do some example practice questions with answers, so I was wondering if anyone knows where I can access some? I tried to find online but I either come across calc questions that involves things and equations I haven't learnt yet or I come across pre reg calc questions.
My uni provides a limited and small amount of questions so far which I have already completed
thanks
