Here are some general trade questions, if you don't know about it, you can choose some of it and remember it. Hope this can help you.
Q. What are trade skills?
A. Trade skills are the crafts of World of Warcraft. You take items you have found off of enemies, bought from vendors, or gathered in the wild, and turn them into something that is hopefully more useful. Many times you can sell these items; sometimes you'll use them immediately.
Q. What are the requirements for trade skills?
A. You can start getting trade skills at level 5. If you need to find a trainer, ask a guard (they'll put a flag on your mini-map if you ask under "Professions"). There are tiers for skills:
Level 5 - maximum skill is 75 (Apprentice - need to be at least 50 to raise).
Level 10 - maximum skill is 150 (Journeyman - need to be at least 125 to raise).
Level 20 - maximum skill is 225 (Expert - need to be at least 200 to raise).
Level 35 - maximum skill is 300 (Artisan - need to be at least 275 to raise).
Level 50* - maximum skill is 375 (Master) - Primary professions can only train in the Outlands
These apply to the primary production skills: Blacksmithing, Leatherworking, Tailoring, Engineering, Alchemy, Jewelcrafting, and Enchanting. There are also three primary gathering skills: Herbalism, Mining, and Skinning. With mining and herbalism, you will get a "track resource" button. Clicking this will show resources nearby on your mini-map as yellow dots. If the dot is gray, the resource is under the ground.
Only accounts that are Burning Crusade expansion-enabled can learn Jewelcrafting. Non-expansion accounts may use items made by Jewelcrafting, though. You can only have 2 of these 10 primary trade skills. You can drop one to make room for another, but if you take it back up later, you will have lost all of your recipes and all of your skill levels. In addition, there are three secondary trade skills: fishing, cooking, and first aid. You can have all three of these in addition to your primary trade skills.
Q. I am level 50 and need to train to 375? How do I get to the Outlands?
A. Only players who have reached level 58 may enter the Dark Portal in the Blasted Lands. But there are other ways to reach far-reaching places, and that includes mages' portals, warlocks' summons, and meeting stones. A player of any level may use those means to reach the Outlands and visit a trainer. (See more about this in the Enchanting section.) You may return to Azeroth using the portals located in the center of Shattrath City or your hearthstone.
