Yesterday I bought a book with the past trial HSC maths papers with worked solutions, but I found another book today that had HSC past papers with worked solutions...
GAH! What have a done and there's a no return policy on study guides/school books in this bookshop :(
Should I buy it anyway...
Or at least have similar questions from past exams. I'm going to do past papers regardless but I just want to know if it will be beneficial.
thankyou :)
