Poor grades in senior three were laughed at by classmates.

If you feel hopeless because he laughs at you, you can only say that you don't live for yourself seriously, but only live for others every day. Go your own way and let others talk. Since God has given talents, let them be used! Everyone is his own strength and advantage. Moreover, learning is only for a better life in society in the future, and it does not mean that learning well will definitely lead a better life. Many entrepreneurs only have primary school education, don't they make their enterprises bigger? Similarly, many college students return to the countryside or work for others after graduation, which shows that learning is not the whole of life. Don't care about other people's eyes and opinions. It is possible to explain yourself with practical actions.
