The Gran Turismo Challenge

As each summer passes, my mission is to crawl closer to the 100% mark in Gran Turismo 4 [I'm at 98.8% as of today] To attain 100% the following tasks must be completed.

• All Gold Medals in the License Series: The License series is a string of events where one is required to complete a lap or a section of a track in a given amount of time. Each stage has 3 times, a Gold, Silver and Bronze time, with Gold being the fastest time and Bronze being a pass. There are 5 levels of Licenses [in order of easy to difficult]: B, A, International B [iB], International A [iA] and Super [S]. The cars, tracks and times are already predetermined for all of them. Licenses are required to enter some races. So far I have all of my Licenses but only all gold in B.

• Completing the Driving Mission Series: These are special races where you are put in a certain situation and required to win. It can be seen as a continuation of the License Series except you don't need to win any to enter any other races. Like the License series, the tracks and cars are already predetermined. There are different classes of missions [from easy to hard]:
  The Pass: This utilizes either one or more corners of a track where you must overtake a car similar to yours. [10/10]
  3 Lap Challenge: This series simulates the instance of trying to win from last place in the final few laps. You have 3 laps to move from last place to first. [3/8]
  Slipstream Challenge: This one requires you to pass cars similar to yours by only using a slipstream maneuver [a slipstream is an area behind a car of low wind resistance, by moving into this slipstream a vehicle from behind will achieve a speed advantage]. [4/4]
  1 Lap Magic: In this you are in last place and are given a start time disadvantage. Within one lap you must pass all 5 cars [all of which are significantly slower than yours]. [11/12]

• Complete the Race Series: These are races with set tracks and laps, in most cases the choice of vehicles are open. There are 4 tiers Beginner, Professional, Extreme and Endurance [as the name suggests this is the series with all the long 24hr races and what not] [completed all races in the series]
  
  
• Complete the Country Races: These are races where you can only race vehicles built in that specific country. in most cases the race tracks are also located in these countries. There is the European, Japanese and American series. [completed them all I think]
  
  
• Complete the Constructor Races: These are races within the manufacturers, not all manufacturers have races and there are too much for me to list. There is usually a list of which of their vehicles are allowed to enter. [completed them all]
  
  
• Complete the Special Event Series: These are the rally races held on wet, tight, dirt and snow tracks [edit: after re-reading this I just noticed the "off" descriptions.] Unlike the rest of the racing series, this does not permit you to use B-spec mode [GT4's autopilot] [completed all of these]

So it's just license and the driving missions left. License first though as those seem easier.
