Back to School 2020 is the third school-related event of Transformice.
You have to complete a series of different tests which include dance, geography and running track. If you pass a test, you receive an A+ item in your inventory. However, if you fail a test, you receive an F item instead. These items can be traded to Prof for event rewards.
In the running track map, you have to press ← and → (or A and D) in turn, repeatedly, to move and increase your speed, while jumping to avoid cannonballs being fired from the opposite direction. Cannonballs spawn every 1-5 seconds. If you press the same directional button multiple times, your speed will reduce. If you stop pressing either directional buttons for a while, you will slow down and stop moving.
You must get to the mouse hole on the opposite side of the map within 30 seconds to receive an A+ item. If you are unable to complete the map or get to the mouse hole after 30 seconds, you will receive an F item.
In the geography map, a flag of a country will appear in the middle of the screen in which you must correctly locate where that country is on a map by clicking. You must get at least 5 out of 8 flags correct to receive an A+ item. If you get below 5, you will receive an F item.
In the dance map, arrows will appear on the classroom board in a sequence in which you must memorise. The arrows will either be pointing up, down, left or right. After the arrows have disappeared, you must press the keys in the same sequence that was shown on the board. There are 3 sets in total, each with slightly more arrows than the last. The first set has 5 arrows, the second set has 7 arrows and the third set has 10 arrows. If you mess up one arrow of the set, your progress is reset to the beginning and you can repeat the same set. If a set times out and you haven't finished (the arrows will shake to indicate time running low), you will fail and get an F item. It is possible to get up to 3 items from this map.
Tip: If you can't remember long sequences, while the game is showing you the directions, type the WASD letter or arrow of each direction in your chat box (e.g. type wasda or ^<v>< for up, left, down, right, left) and since everyone has the same sequence, you could post it to help others. You could also take a photo of the screen showing all the arrows using your phone.
