Summer 2019 IB Application Question

I go to a state target school and the application deadline through our career site for most internships for 2019 is approaching rapidly. I don't know exactly what I'm going to be doing in the summer of 2018 yet (I have one FP&A offer at a small corporate office, but i'm still waiting on a few boutique banks to let me know my status). Should I still apply as soon as possible to these jobs or wait a week or two to make sure I have something down for my summer '18 role? Thanks
