I am with Mariest
I am not a guru neither an OCP but I consider experience over certification is better. You might wonder why, simply because certification is academic.
I used to have a friend who was really good at Maths because he spent the wholeday doing exercises but same style of exercises unfortunately when the style of exam changed he couldnt do it at all.
A while back someone posted in this forum saying that he is an OCP but he couldnt answer any of the question which were being posted in the forum and he was requesting for some advices of how to deal the kind of qwuestions that are been asked here
I am planning to take OCP exams but just to boost self confidence and learn details that I probably never use
