I'm going to disagree. I believe that unless you take fairly substantial action quickly your chances are quite poor. Taking another test like the ACT is unlikely to change this.
Drexel is a Common App school, and I think Penn State might be as well. Common App requires an essay. Judging by your posts here and by the score on the writing portion of the SAT, your writing skills are substantially below what even moderately competitive colleges and universities require of entering freshmen. I say this not to be mean, but to focus your attention on something that will keep you out of good college unless it's rectified.
Admissions offices usually don't weight any individual piece of evidence very highly - they are looking for patterns. If your essay looks like the writing samples you've posted, and you finish in the 5th percentile in the SAT writing portion, that's a pattern.
If I were you, I would be working day and night to improve my writing. I would be writing essays every single day. You have a few months to make the same improvement to your writing that takes many people several years. They say practice makes perfect, but in fact, practice makes permanent. You would have to make it a point in all your writing (including here) to use proper diction, capitalization, spelling, grammar, etc.
