Many opportunities in graduate school require that you write up why you want the money that is being extended.  Grants are highly competitive and you don't want to miss your chance just because you did not understand some of the important considerations that will be covered in this session.  You may have the best idea in the world and still lose to someone else because of technicalities, language mistakes or not understanding the mechanics of a good pitch.  Come prepared for this event with your grant guidelines in front of you so you can ask specific questions through https://www.wooclap.com/grantwriting
