Concerns about graduate school

The school I would really like to go to has the following note about Philippine schools:

 Master's Minimum Admission Requirements:

    * Four year Bachelor's Degree Equivalent: All Disciplines - Completion of both Bachelor`s and Master`s degrees with first class standing

    * Mid-B Equivalent: 1.5 (reversed scale)

I think I will need to take the GRE CS test to help reassure them (and
me!) of where I am in terms of education. I hope that and strong
letters of recommendation will be enough. I’m not sure.
