First of all, are you male or female? If female, I may advice that you begin to look for other options as you may miss out on other important aspects of your life. If male, you may want to consider it more deeply. Fine you have a good result and everything but believe me, there are many out there with better credentials and with less opportunity. This 64k may seem ridiculous to you because you see what other are earning around you within the same bank, but if you look without the picture is not so different. As for your brain being stale, aw come on.... is that for real? If you really want to leave then reactivate it by all means. I had a friend who suffered same fate in UBA. She worked for three years with an OND certificate even after earning her B.Sc. She eventually got converted to Customer Care Officer after taking their examination. Study hard (by all means) and take the next exams that's what I think. Stick with it, it will not last forever.
