Seoul Line 2 is a major circular route connecting business districts and universities. Its loop shape makes a few strong anchor stations especially useful.
Do not memorize the loop in one go.
If you try to memorize the entire line 2 at once, the order will often get mixed up. Take familiar major stations such as City Hall, Hongik University Entrance, Sindorim, Gangnam, Jamsil, and Wangsimni as reference points and divide the stations between the reference points into small bundles.
Distinguish between internal and external circulation directions
If you just memorize the station name, you may get confused when taking the train in the opposite direction. Before starting the game, check the direction first and remember the previous station and the next station as a set. In the Guro Digital Complex area, stations on both sides are connected together, like Sindaebang and Daerim.
Check order by typing
Look at the route map and then enter the station names in order. Even in sections that you have been looking at without any hesitation, if you have to write the answers yourself, points where your memory is ambiguous are revealed. It is easy to correct the connection order by re-entering the wrong station by tying it with the two stations before and after it.
Make a record of one section every day
Rather than aiming for quick completion from the beginning, it is important to create the correct order first. Try short challenges once or twice a day, and once you get used to it, reduce your typing time. The more you repeat it, the more stable the station order and Hangul typing rhythm become.
