Public College daw?

Isang kahit isang tuka na nga lang lalo pang pinahihirapan sa pag aaral kapag sa probinsiya ka nakapagtapos ng High School. This is what I experienced when I'd tried to enroll my sister who is already 23 years old and tried to enroll in Public Tertiary schools in Manila such as PLM and CCM. PLM accepts any students who graduated outside Manila as long as it is Manila's residence with an average of 85% or above for the 2nd grading period in High School. Too bad because my sister got only an 82% average for the whole grading in H/S. Another one, how can I get the ITR of my parents if my father is only a laborer on a farm in the province. Is it valid even it came from a province? I don't know for sure.May edukasyon ngang libri para sa mahihirap. Hindi naman para sa lahat!
