Should I drop my fourth subject?

I'm currently studying A-Level Media studies, Film studies, and Level 3 BTEC IT. I got a B in Media, a B in Film studies and a distinction in IT (I get another grade next year). I was thinking of dropping film studies because i feel a fourth subject may be harder to handle in my second year of A-Levels. I also feel that I don't enjoy Film studies that much.

Would it be wise to drop film studies?
