After much thought and discussion with a few peers, I've decided to continue on to the next part of the course, and have booked a slot on both M263 and M255 (Building Blocks of Software, and OO Programming in Java respectively).
Being a software tester by day, and a late starter to higher education, i've contemplated the worth of doing a degree, as it may take me another 5-6 years to complete. That being said, I've decided that the long-slog should eventually pay off, if nothing more than to secure a higher paying managerial position when I'm 30+.
So, it's back to the books this autumn. Pleased to have completed the Certificate however.
Best of luck to all, and see you in the student rooms later in the year.
