WAEC Examination officer Computer services/Computer Programmer in Fed ministry???

Hello House,
Few months ago, i got a job with a Federal Ministry as a computer programmer, and fortunately for me i got my long awaited Job with Waec as Examination Officer Computer Services. I am so confused on which to choose. Your advices with reasons will be highly appreciated. The Waec salary is almost double the Salary of the ministry, but i was told that one grows faster(Carrier wise) in the Ministry than with WAEC.

When did they call you? I did the same interview last yr Sept buh havent heard from them. How were you contacted? Please reply.
