 ### Summary of Contributions
 
-- `add_student` command:
-    -  Allows professors to add a student (with parameters `name` and `matriculation number`)
+- **New Feature:** `add_student` command:
+    -  What it does: Allows professors to add a student (with parameters `name` and `matriculation number`)
        to the registry of students in the application.
-    - This feature allows professors to input all students in their course into the application.
-- `delete_student` command: 
-    - Allows professors to delete student using `matric number`
-    - This feature allows professors to remove students should they withdraw/drop
-    the course.
-- `find_student` command: 
-    - Allows professors to search for students using
-  either `matric number` or `name`.
-    - This feature allows professors to quickly search for students in their course.
-- `list_student` command: 
-    - Allows professors to list all students in their course65
-    - This feature gives professors a quick and dirty overview of their students.
-
-- `delete_component` command: 
-    - Allows professors to delete a component (exam, assignment, class part etc) from the app
-    - This feature allows professors to remove components that are entered incorrectly or are 
+    - Justification: This feature allows professors to input all students in their course into the application.
+    - Highlights: Implementing input validation for entering matriculation number (checking that matric number complies
+with given formatting).
+- **New Feature:** `delete_student` command: 
+    - What it does: This feature searches for and deletes students from TutorLink.
+    - Justification: This feature significantly improves the product by allowing professors to remove students who have withdrawn
+      or dropped the course.
+    - Highlights: Remove all grades associated with the student when executed. This is because a `Grade` object is only 
+  well-defined when it is tagged to a corresponding `Student` object; removing the latter should automatically remove the former.
+
+- **New Feature:** `find_student` command: 
+    - What it does: Allows professors to search for students using either `matric number` or `name`.
+    - Justification: This feature allows professors to quickly search for students in their course.
+- **New Feature:** `list_student` command: 
+    - What it does: Displays a list of all students in the course. 
+    - Justification: This feature improves the product significantly as professors receive key information about their students 
+  such as their `matric number` and, more importantly, their current percentage score. 
+    - Highlights: We faced challenges devising a suitable method to store and update the percentage score that would hold 
+  across all other operations that could affect it, i.e `add_grade`, `delete_grade` etc.
+    - Credits: Special thanks to @ThienDuc3112 and @yeekian for making this feature possible through their work in the
+  `add_grade` and `delete_grade` command. 
+
+- **New Feature:** `delete_component` command: 
+    - What it does: Allows professors to delete a component (exam, assignment, class part etc) from the app
+    - Justification: This feature allows professors to remove components that are entered incorrectly or are 
 no longer part of the course.
+    - Highlights: Similar to `delete_student`, `delete_component` removes all grades tagged to the specific component upon
+  execution. This is because a `Grade` object is only well-defined when it is tagged to a corresponding `Component` object; removing the latter should automatically remove the former.
