First of all, the question was "what are some resources," not "what should I do." A CFAR workshop is one option of many (although it's the best option I know of). It's good to know what your options are even if some of them are difficult to take. Second, that scholarships are limited does not imply that they do not exist. Third, the cost should be weighed against the value of attending, which I personally have reason to believe is quite high (disclaimer: I occasionally volunteer for CFAR).
