Mega Man Battle Network Tips

School Network Codes
In the school network, there are doors that you will come to in which you'll need to enter various 2 digit passcodes.
Some doors have randomly generated codes, and the game gives you hints based on what numbers you enter whether the code is higher or lower.

1st door: 09
2nd door: 30
3rd door: randomly generated
4th door: randomly generated
5th door: 15
6th door: randomly generated
7th door: randomly generated and requires "teacher's passcode" to access
