It’s sad you feel that way I had the same issue, a d7 in maths, I also gave alms and prayed and fasted my dad gave me an ultimatum to apply to the polytechnic in Ghana because they accept d7. I told him no I couldn’t bring myself low after attending good schools. After unending arguments at home I had no option but to apply. I finally gained admission and went there for 3 good years, none of my friends knew where I was because I was too embarrassed to inform them. Now I’m doing my top up in business administration in a well known university, hopefully next year I’ll be done. Sometimes we can’t get things to go our way so you have to improvise with the situation and make decisions that would help you in future. God listens and probably has a better plan for you please don’t give up.
