To take or not to take Grades Test/Exams?

Recently, I'm debating whether or not to take grades test/exams when the time comes around for it. XH says, I probably should - since I spend that much already on lessons ... and my mom was like: no need to go for exams lah, just know how to play a few songs can already ...

personally, I hope to attain a cert eventually ... but I am not so confident of myself. Last night, I was comparing between Trinity and ABRSM Exam syllabus again ... Eventually, I come to the conclusion that if I were to attain a cert - I might go for ABRSM.

Why? - Simple, first of all ... their directions/instructions are simple enough. Trinity seems more complicated ... Second, you can get information and stuff (such as exam pieces) more easily - as compared to the specified pieces for exams from Trinity.

Right, anyway - its' still too early to be thinking about the exams - since I'm only at the stage of the beginner. Well, I'll blame it on XH - since she was always talking about the grades exams and all... :P
