Hey guys, I have searched the topics posted before but I would really like the experienced ones among us to give a very honest opinion about this. Are the question books offered by CISA COMPLETELY different every year ?
I am a student under heavy financial burden heading into my 4th year, studying at a very good university and have been to find someone who is providing me the 2015 review manual and question bank for a relatively much cheaper price.
So what do you think? With very hard work and the 2015 question bank, can I pass the exam ? Or do I need to sell something so I can buy the 2016 one ?

I do not want to risk my chances but at the same time, if the question books are just for practise to give us the pattern of the final CISA exam, then I don't think I need to buy one. Please help me out
