Applying to Penn ED WITHOUT taking ANY SAT subject tests?

I am planning on applying to Penn for early admission, but I haven’t taken ANY SAT subject tests and I’m taking the SATs again in September. I know I should’ve known before but I recently decided to apply to Penn (before I thought I didn’t have a chance)
How bad is it? I know it’s not required, but how bad will it make me look? Can I take them after the ED deadline and submit them later??
BTW- I plan on majoring in political science

Subject tests are recommended which mean that unless the rest of your application makes you a shoe in or you are a legacy, they are “required”.
