- For those who want to consistently get an A+ in the algorithms/data structures class by preparing beforehand.
- For those who gave up while studying algorithms/data structures because it was too difficult.
- For those who have some experience studying algorithms/data structures, but want to refresh their concepts because they are not clear in their mind.
- For those who need to study algorithms/data structures but don't know where to start or how to study.
- For those who don't know much about algorithms/data structures even though the coding test date is fast approaching.
- For those who are reading the explanation of past coding test problems but are unable to understand due to not knowing the terms.
- For those who have learned coding before entering a gifted high school, but still do not know much about algorithms/data structures.
- For those who are unable to understand the explanations for USACO Silver exam problems due to a large number of unfamiliar terms.
