SM & JYP QUESTIONS~ :D?

No one really knows except them. They will see when you are ready. And also see when others are ready. When you AND your friend are ready in about the same time (like maybe some months apart or being ready to each other).And they might keep training you even if they think your ready because you need more than 1 to make a group. Then they see if you guys are compatible and put you guys together with others depending on how many people they want in the group. and you all train together for a while and then debut!
