 ** The application relies on precached NUSMods data of all existing tutorials in AY 2019-2020, hence it does not rely on a internet connection.
 Even then, the loading of the all the data into T.A.rence at initialization is not too computationally/memory intensive, without significant lag.
 This is partly because extraneous elements (Lectures, Venues) have been filtered out in the cached data to reduce file size.
+** Retrieval of NUSMods tutorials after the initialization is also efficient since the cached data is loaded into a data structure of nested HashMaps that has keys in the following order:
+Module code, Semester, Lesson Type(Sectionals, Tutorials, Labs) and finally a unique ClassNo.
+** The primary challenge in implementing the importing of tutorials was ensuring the compatibility between the cached data and the Tutorial Class already defined in Application.
+This required delving into NUSMods data to understand the general structure of the JSON, as well as reading existing API documentation.
