I'm gonna take Magento Certification exam in next 3 months to become a Magento Certified Developer, I've been searching for document for this exam. When I look at the study guide I see a lot of questions which I can answer, however the problem is I don't really know what they are expecting me to answer.
I would like some materials that provide real experience on this exam (it's best if Ebook is written by Magento Certificated developer)
I highly appreciate any suggestion/recommendation on this. Thanks in advance
