 ## Predicate Utilities
 * A _predicate_ is a clause which states something about a subject. (_e.g., **is assigning**_ in _"Leon **is assigning** homework"_)
-* Ensure each of the test cases passes successfully in the class [TestPredicateUtilities](https://git.zipcode.rocks/ZipCodeWilmington/ZCW-Lab-Fundamental-Methods/src/branch/master/Method%20Fundamentals/PredicateUtilitiesTest.java) by completing each of the method stubs in the class [PredicateUtilities](https://git.zipcode.rocks/ZipCodeWilmington/ZCW-Lab-Fundamental-Methods/src/branch/master/Method%20Fundamentals/PredicateUtilities.java).
+* Ensure each of the test cases passes successfully in the class [PredicateUtilitiesTest](https://git.zipcode.rocks/ZipCodeWilmington/ZCW-Lab-Fundamental-Methods/src/branch/master/Method%20Fundamentals/PredicateUtilitiesTest.java) by completing each of the method stubs in the class [PredicateUtilities](https://git.zipcode.rocks/ZipCodeWilmington/ZCW-Lab-Fundamental-Methods/src/branch/master/Method%20Fundamentals/PredicateUtilities.java).
 * Method Stubs to be completed
 	* `boolean isGreaterThan(int x, int y)`
 	* `boolean isLessThan(int x, int y)`
