I hear so many questions on 100 about building up license level, so I did some experimenting for the Combat, Light, and Heavy. Here is a fast way to get them built up.
-Do the Courier mission and get a Revenant.
-Do Beginner Combat Practice - concentrate on Oruns on this run and collect Orun Cores and scrap metal. I would try for about 20 or so Cores. If the mission tells you that you get no more bonuses for Orun, you can stop the mission and restart it again.
-Do mission Rogue Drones - it ask for some Orun Cores that you have already collected.
-Do mission More Orun Processors a couple times using the Cores you have collected.
-Do mission Beginner Combat Practice again - concentrate on Dentek this time and collect the Cores. I would try for about 20 Cores and some scrap metal.
-Do mission More Dentek Processors a couple times using the cores you have already collected.
-Do mission Intermediate Combat Practice concentrating on Artemis and collect the cores. You will need to collect at least 32 Cores. You should have enough scrap already, but can always sell the excess later if you want to collect some more.
-Do mission Alternate Avenue of Inquiry. It will take you to another station and ask for Artemis Cores.
-Do mission Artemis Core Sweep a couple times. It will ask for 15 cores and 20 scrap for each mission. Hint - you do not have to use Scrap Metal that you collect from Artemis on this mission, any scrap will be accepted.
-Do mission Aurum Potestas Est. It will ask you to carry findings to another station and then back.
I did all this with Rev and weapons that a FTP player can obtain. I used Hive Fast Cell (which a lot of players will give you) and Plasma Cannon HX (1/1/-/-/-). For Heavy you can use the Stingray Missile till reach Heavy 1 and then use Plasma Eliminator, Unless you can find a Hive Queen Gatling Cannon. Also a Ultra Charge Power Cell can be used if you can buy one from someone or from a Player Store.
At the end of this, depending on how many bots you kill with heavy weapons, you can have up to 4/3/3/1/0. You can go back and shoot Artemis with Heavy or Light to get that level higher when ever you want. I did all this in less than a couple hours, but time can vary depending on the drop rate of Cores from the bots.
Hint - - I cut my speed down to about 1/3 when near the bot area and used straft, either left or right, when Dentek and Artemis came at me. Keep them in your crosshairs and shoot and they won't hit you that much while you strafe.
When you get ready to build up the Mining Level, find someone to give or sell you some High Density Mining Beams. They will well pay for themselves in mining speed and are the best overall beam in game.
When you get ready to build up the Trading Level, get the largest cargo capacity ship you can and do the Trade/Procurement missions. Hint - the ones that ask for the largest amount of stuff and the longest trips (Bulk) pay the most and give the highest amount of experience for your levels. After doing some for a while, you may remember the locations of some of the items, as normally there will be one item they ask for a lot, and you can buy from a different station than the one they suggest. Also, buy a ship load at a time as you can use the extra to fill out a mission later without even having to travel.
