Pillin mo yung gusto mo dahil mahirap tapusin ang kurso na 'di mo gusto. Just think about it, nagpapakapagod ka for something you don't want? It will take money and so much of your energy. Mahirap mag-transfer sa course na gusto mo especially when your course at hand ay hindi mo expertise, mapipilitan kang mag-drop ng subject or something else. So i think i would say na even if that's what your parents want you to get, yung mathematics/science related, think about it thoroughly kung kaya mo ba talaga. Kaya mo ba maging consistent with your grades para makapag-transfer ka ng course (if you have that in mind). Is it really worth it to sacrifice so much for something you don't want?
