BIM, the acronym for building information modeling, is a technology. I translated it into building model informatization, and some teachers translated it into modeling information model, depending on personal understanding. These two words are not in the same order, and there is a little difference in understanding. The key point I understand is the informationization behind them.

BIM is the general name of a technology, which takes a specific workflow as the carrier, uses various information software to informatization construction projects, and promotes the development of social informatization.

If the subject is Revit, the Revit exam mainly examines the operation and modeling ability of the software. Just learn more and practice more. You don't need much experience.
