Passed Exam Successfully

I have been working in Employee Central and other SF Modules for the last 2/3 years and was never confident to take the Employee Central Certification exam. I know how to do things in EC very well but the academic part of where to find what, what can you do before certain things as recommended by SAP, etc. were completely missing for me. 
I have been looking for some practice exam questions and found ERPPrep highly recommended. I purchased the Employee Central exam test just two day before, started with the Mini test version. Ater few successful pass, I took the exam which is similar to actual exam containing 80 questions. From the beginning I scored above 90% and few 98% as well, so decided to take the real exam. 
Purchased the SAP Certification Exam subscription, scheduled an exam for today afternoon and passed. Hurray!!! 
I highly recommend ERPPrep.com Please note, there will be some 10% to 20% questions differently presented during the actual exam, but they are almost similar to the test questions provided by ERPPrep. 
I am going to buy other module exam tests from this site and take those exams as well.
