I completed my Salesforce certification on Developer 401 Spring'15 . After that, i cleared two Release Exams (Summer '15 & Winter '16) without paying any amount. Now, i have to write Spring 16 exam paying 100 USD. My question here is, for Summer '15 and Winter '16, i just got 5 questions and i cleared it...Can i expect the same for Spring '16 as well? or will be getting more questions? Kindly advice on how to get prepared for this exam.
Thanks so much in advance!
