In Forza Horizon 6, Bonus Boards / XP Boards are a type of collectibles with which you can gather some experience relatively quickly. There are a total of 200 Boards in Forza Horizon 6. In order to score a board, all you have to do is simply drive through it and destroy it. They can be divided into three groups, depending on how much experience you get after destroying a certain board.
There are a total of 100 XP boards that will grant you 1,000 XP, and they are usually very easy to get, for example they are located near roads, etc.
The second group are the boards which will grant you 3,000 XP and are a bit more difficult to find, for example they are hidden behind buildings or in desolate places. There are 75 such boards.
The last group are boards that will deliver 5,000 XP. There are 25 of them. Some of them are easily accessible but many of them are in hard to reach places. You will have to use nearby ramps or terrain to jump in the air to get to them, etc.
In total after collecting all the XP boards you will get 100 * 1,000 + 75 * 3,000 + 25 * 5,000 = 450,000 XP.
Note: To reach certain 5,000 XP boards, I myself used an unmodified 2018 Subaru WRX STI ARX Supercar, which is the reward for completing the Launch Control (Purple) wristband event. Of course, there's nothing stopping you from using any other car.
