Well it will give you a more thorough understanding as if you dont take the course you wont . I took a met 101 class, and a Intermediate class. Mostly the 101 course is basically knowing the stuff you should know to obtain a pilot's instrument license. Such as what is an adiabatic rates, Pressures, components that creates a thunderstorm, Understanding Lows/Highs, Types of Fronts, All Types of Wx Charts, Different types of fog and what creates them, Icing/ types of icings, etc thats the 101, the Intermediate course was more indepth into prognosticating weather patterns. Bottom line if you need it as an elective by all means take it, but if you dont I believe the knowledge from the instrument course should suffice.
