Tanny,
If you need a job, something to do with healthcare, then consider nursing, or RT, or PT, or whatever. But consider it will slow down your application to med school and will probably not help when you apply apart from giving you clinical hours. However, if you need to eat and pay student loans until you are ready to re-take the MCAT a couple of years from now, well, then that might be the right choice. You could also find a job waiting tables or something that has a high income to hours worked ratio that will allow you to study for the MCAT and try again sooner. We don't know your financial situation. You need to decide what is most important. Do you think you could take a course and get a higher score on the MCAT? Are you desperate financially? These are the questions you need to answer. If the answer to the first is no, then do whatever you think will make you happy. If the answer is yes, then find a way to get it done. Whatever you choose to do, with hard work things will most likely be ok!
