I got CSS in biology stream English medium in my second attempt. What can I do now?? Urgent replies plz

Actually my family is not well off. I am thinking of even doing 3rd attempt because I want to go to either Colombo and japura science faculty. Then I can build up my own path. I got sff in my first attempt - 2023(s for physics) I couldn't go to proper classes in both of my attempts due to lack of suitable em classes and high cost of money . Second attempt was in 2024 and I got css c for physics I just wanted to know what are the good options available for me right now with my current qualifications
