I was wondering if anyone in Ontario has experience with Isa's cert arborist exam. Ive decided to write the exam at one of there new computer testing centers. (PearsonVue). I could probably write it today and pass but u never know. They reccomend their study guide (at $95) but warn do not rely on the study guide alone. On their website they give a list of reccomended materials which looks pricey. Anyone else been through this?
