I decided not to play Varsity tennis this year... should I email saying this?

<p>One of my EC’s was the following : 3 years of tennis in high school: JV in Freshman, Varsity/JV half-half in Sophomore, nothing in Junior, and Varsity senior (I’m 100% confident I’ll get a varsity spot for this season).
Now that I’m looking at my course-load and so on, I really don’t feel like I can manage playing for the team. Will dropping a year of varsity tennis hurt my chances? Will not letting the UC system that I dropped get me rescinded (I hear audits are in mid January but tennis season starts the 6th of January)? Thanks so much for your advice!!!</p>
