Take a look at some of these threads that have dealt with older applicants applying to allopathic schools:

Anonymous student, I think another big problem you will have is the fact that you are a California resident. While your MCAT score and GPA are both excellent, CA applicants do need to have higher scores to gain admission to medical school. CA-friendly schools to consider would be Tulane, Boston U, Tufts, MCPHU, Albert Einstein, St. Louis, NYMC, and many of the other private ones. Some of these schools have as much as 50% of its incoming class from California. It's often been said by Adcom members that California's greatest export is medical students.
By the way, I've read a couple of your posts and the problem you have seems to be specific to your school (average COMLEX scores and one of the Biochem professors). You may not feel the same way once you are in your clinical years or at least it won't be important anymore. Students from your school do well in both the allopathic and osteopathic match - this is ultimately what is most important. Do not let your emotions guide your decisions because you may end up regretting it. If you really can't continue at Western, you can always try tranferring to another allopathic or osteopathic school. Why waste two years for nothing? Best of luck with your decision.
Here's a thread that deals with DO to MD transfers:

Pags, the advice about Western is probably the last thing he/she wants to hear.
