README.MD

+# Quiz 1
+You have one hour to complete this quiz. You are required to do section 1 & 2. Section 3 is a bonus section, which means do it if you finish the other two sections before the hour is up.
+
+### **Instructions:**
+
+1. Fork this Repository
+    * [fork](https://help.github.com/articles/fork-a-repo/) this repository to your personal github account
+    * [clone](https://help.github.com/articles/cloning-a-repository/) **your** `forked` repository to your local machine
+    * Write the code to make all the tests pass. See below for instructions.
+      * MAKE SURE YOUR CODE COMPILES
+      * Run the test to verify your code
+    * `git add .` to add files you want to commit
+    * `git commit -m "commit message"` to commit your changes
+    * `git push` your staged files to your remote repository
+    * submit a `pull request` which compares Zipcoder `master` to your `master`
+
+## Section 1 - MathUtilities
+Make all the tests in the `MathUtilitiesTest` class pass. All the methods have been stubbed out for you in the `MathUtilities` class. Each of the method has a comment above it to describe the expected behavior. Look at the test case to see example of input and expected output.
+  - `int add(int num1, int num2)`
+  - `double add(double num1, double num2)`
+  - `double half(int number)`
+  - `boolean isOdd(int number)`
+  - `int square(int number)`
+
+## Section 2 - StringUtilities
+Make all the tests in the `StringUtilitiesTest` class pass. All the methods have been stubbed out for you in the `StringUtilities` class. Each of the method has a comment above it to describe the expected behavior. Look at the test case to see example of input and expected output.
+
+  - `Character getMiddleCharacter(String word)`
+  - `String removeCharacter(String value, char charToRemove)`
+  - `String getLastWord(String value)`
+
+## Section 3 - Bonus
