I don't know how many units/credits your school requires, but there is an online course via UCSD Extention. I believe they have a course starting in March. But since they are on quarter system, the class is only equal to 0.67 semester units. Some schools may let you take it anyways and count it towards your prereq - all depends on the admissions office's discretion so talk to them and see if they will take it.
I actually just finished the course through the UCSD extension. They are still enrolling students for the course. Although it started in January, you actually only have three weeks to complete it- no matter when you start. I believe March 22nd is the final day to end the course. It was pretty straightforward, 14 quizzes and one final (all were open book/notes/online access). It may sound a bit intense (with the amount to do in three weeks) but I ended up getting through it in about two weeks. I hope this helps!
