Bago ka mag start mag self-study first you should decide what do you want to pursue. Either gusto mo maging Game Developer, Website developer, Mobile apps developer, Networking, etc. Search different types of programming language then try to understand kung saan kadalasan ginagamit yung Programming Language na yun. Mahirap mag suggest ng Programming Language kasi wala ka pang na-encounter na programming lessons.
Also, ask ka kung anong programming language or lessons ang ituturo sa inyo sa upcoming school year, para dun makapag-advance ka. Btw, I'm Second Year College this year at sana makatulong ito.
