LP2415: 4 Weeks Refreshing Package, 24w15

This package is designed for a bigger group of students involving experienced students from previous Learning Packages up to LP2408, and some newcomers with zero prior knowledge. The main motivation is to let the existed students slow down a little bit, refresh and spare the learnt knowledge, and help the new friends to ramp up basic starting knowledge. Part of the key knowledge points are the same as LP2313, but the arrangements of contents and hands-on projects are made a little different, so to fit both the experienced ones and fresh newcomers, it won't be boring! And, we learn deeper when reviewing, repeating and helping each other!

This package is well completed in week 18, below information is already updated based on the actualized activities, so to document what we have achieved.
