You didn't get all the questions right but that's expected. You knowledge level is what is expected from a CS graduate. (Heck, its better then what I knew when I graduated from my BSc).
In your position, I would consider the following paths:
1. Go to your relative's computer shop while building up your portfolio and some extra self learning. I did something similar and worked at my cousin's workplace for a year while I sorted out what I really wanted to do.
2. Attempt to get a standard programming job to build up experience and still work on the portfolio.
Either way, I recommend reading up on the C++ Standard Library and the books Effective C++ and Code Complete. C++ for Game Programmers is also worth a read.
Edit: Forgot to mention, start looking at making contacts in the industry. See if you can find a local IGDA chapter to go to.
