Do i still need to go for test(s) now?

why not thats the only way u can prove ur more than a 3rd class but maybe u were unfortunate to have been given it. Its nit easy i must tell u,my last experience was with oando plc after a professor gave me her contact ,she examined my c.v and asked what i graduated with immediately i told her she threw my c.v and said it was there company policy not to employ 3rd class 2 show d stigma attached to it,i wonder why they still issue it in the universities. God dey sha!!!!
