Definitions

Many of you guys who have taken the L1 exam say that there were a lot of questions on general terms/definitions. At the end of each of the CFAI books is a glossary of key definitions. Would it be beneficial to spend a fair amount of time reviewing these?

Although I haven’t taken the exam, I would concentrate on only the subjects they ask you to define in the LOS. Afterall, that is all they say is required for the exam.
