I have been thinking of upgrading my self academically but procrastination is always on my mind since 6 years ....I am currently working but I think its high time I upgrade myself, but I have E8 in my mathematics that has disfigured my waec result and I have not resit for that since then, and I have already run a course at Babcock school of security management , so now I have diploma and certificate in security ....now I am thinking of getting a degree but I have to work to sponsor myself..
What should I do now pls , I want good advice
God bless u
