GPA 3.0 is around or even below the average. If this is a larger scholarship that the school only gives to the top couple percent of students, they do not expect you to drop below average. GPA 3.0 is a very reasonable renewal requirement and it is not hard to achieve for those who received the scholarship at the first place. My D got a top engineering scholarship in a very competitive engineering school with the same renewal requirement. Even she started her freshmen year with mostly sophomore classes, it was never a concern to go below that requirement. You should feel more confident and not to worry about it too much, unless that GPA 3.0 is already well above the average.
