What the 3-in-1 2nd class quest is
The 2nd class needs three marks — one each from a Trial quest (level 35), a Testimony (37) and a Test (39). Every class has its own set: Gladiator needs Challenger, Trust and Duelist, Bladedancer needs Challenger, Fate and Duelist. Doing the quests one by one sends you to the same places several times.
The 3-in-1 route starts at level 39: you take all three quests at once and finish them in a single run, combining monsters and NPCs from different quests in one trip. You change class at level 40 with the guild master of your class — each guide names the exact NPC. Taking the mark quests for the first time also gives Dimensional Diamonds.

What does 3-in-1 mean?
You take all three mark quests at level 39 and finish them in one route, combining shared locations. It is faster than doing the marks one after another.
Who changes the 2nd class?
The guild master of your class in a big town, at level 40 with all three marks. He takes the marks when you change class.
Can I get the 2nd class without quests?
Yes, if the server has a Class Master: it changes your class for adena and no marks are needed.
