Okay, let's start with true meritocracy.

Horikita and the former first-year students of Class D, who have passed the "end-of-year special exam" at the end of their second year, are now in Class A.
However, the greatest contributor, Ayanokouji Kiyotaka, changes classes.
The Horikita class students were thrown into confusion and chaos── but there was one cruel truth.
Horikita and Class 3-A cannot graduate from Class A unless they defeat Ayanokouji Kiyotaka.
As new connections are formed between Ryuen and Class B, Ayanokouji and Class C, and Ichinose and Class D, the first special exam for third-year students, the "Group and Small Group Comprehensive Academic Ability Test," is announced! Only one class can graduate as Class A.
Which class will rise to the top? The long-awaited "3rd Year" begins!
