I was 18th year when I graduated from secondary school in the year 2015 i got my o-level result and i wrote Jamb in 2016 i secured 200 above i applied medicine and surgery and I the didn't offer me admission. I didn't give up i applied polytechnic and my dad is not willing to support me as then i had been applying for different schools sometimes I got d admission but still he didn't pay for it, i stay 5yrs at home am not schooling neither empowered and now i got admission in polytechnic i work hard and earn some cash but I can't complete the registration  Due to lack of funds now i decided to cell my smartphone to use the money and pay for my fees
