Career prospects with yearbacks.

I'm a final year CS and I'm wondering how to go about looking for jobs. I have three yearbacks but with no current backlogs and I'm already not eligible for more than half of the campus placements. How do I go about looking for more jobs that have no criteria? Will writing eLitmus or AMCAT boost my chances in any way because my aggregate is definitely below 60%. My 10th and 12th grades are above 70% if that makes a difference. I also have decent knowledge in Java, C++ and Android programming.

If I could get a few tips on how to proceed from here I'd be thankful.
