Should I take a C or the W?

I’m currently taking physics and organic chemistry at a junior college with the hopes to transfer to UC or state college next fall. I have a 3.30 gpa and am considering dropping Ochem as it looks like at best I can get a C. I have 4 Cs already and 2Ws, I know this isn’t the greatest situation. But I’m wondering if I should keep going and aim for the C and lower my gpa or take the W and explain why I have 3Ws. My ultimate goal is to become a dentist or dental hygienist. Any advice would be appreciated! Thanks in advance.
