How do I overcome Spring Slump (Highschool) ?

I’m currently a sophomore and I realized that the Spring semester is always hard for me.School ends in 3 weeks and my grades are not near as where I want them to be. The fall semester I had As and A minuses and this semester I currently have only 2 As and the rest are Bs or B minuses (YIKES!!). It’s not as easy as the fall semester. I don’t put in the effort that I normally put in during the Fall semester. Any tips to overcoming this ? Tips to avoid this ???

Take a couple days off to refresh yourself and push through it.
