Famicom Grand Prix F1 Race/Race track overview

Level overview
There are 10 different race tracks in the game. They are combined in groups of four. The last two track from one level make up the first two tracks of the next level. There are four different levels of difficulty to compete at. Each level increases the challenge by pitting you against more competitive and capable cars. So even though you race on, for example, circuit 3 in both level 1 and level 2, you will find it more difficult to stay ahead of the competition with the same car in level 2.
 * Level 1: Level 1 is your chance to get used to the controls and how the cars handle. Practice these four tracks until you have a good feel for how to accurately steer the cars, and when to apply Turbo for cars equipped with the ability to use it.  You will be forced to start by using one of the cars in the first two rows.  Expert players who are already familiar with the mechanics of the game, and are good at avoiding collisions with other cars, will find that car #6 is more than adequate to come in first place on all four tracks.
 * Level 2: By Level 2, 500 PS and 600 PS engine cars will struggle to keep pace with the rest of the pack. Even Non-Turbo 800 PS engine cars will have a tough time.  For this level, Turbo capable 800 PS engine cars or Non-Turbo 1000 PS engine cars are your preferred choice.
 * Level 3: Once you reach Level 3, you should no longer count on coming in first place all the time unless you are able to build up a significant amount of cash for a good car. Non-Turbo 1000 PS engine cars will need to race near perfectly to come in first place.  Turbo capable 1200 PS engine cars stand a much better chance, but they are expensive to come by, and can be difficult to control.  In addition, you will need at least one wet-tire capable car for Circuit 8.
 * Level 4: Until you can save up the 5 million dollars required to buy one of the cars in the final row of the shop, you should not expect to do very well in this level without a significant amount of practice. Your competition will be driving as fast as possible, and they don't need to worry about stopping in the pit for repairs.  To make matters worse, you won't even be permitted to examine the last row of cars until you at least complete this level by placing sixth or better on all four tracks.  You'll need a Turbo capable 1200 PS engine car to do just that, as well as a good wet-tire car to handle circuits 8 and 10.
