tax returns as a student and financial aid

[BanzerPop]

does anyone know if you can put yourself as a student somehow on tax returns if you are studying for clep/dsst etc 24/7 as a fulltime job?
does anyone know if there is financial assistance either for the CLEP/dsst etc tests themselves or for the tesc/coc/exe tuition?
i am pretty sure these answers are elsewhere in the forum or internet but just wondering if anyone knows off the top of their head (i will search on my own if no one can help) thanks
