What this page is set to
This page opens with the timer already set to the values below. Nothing to configure — just press start.
One full cycle of 2 focus sessions runs 220 minutes, 160 of which is focus time. Fill an eight-hour day with this split and you spend roughly 5.8 hours focused across about 4 sessions.
You can change any of these numbers under timer settings. Changes are saved for this page only, so they never overwrite the settings on the home page or on another preset.
- 80-minute focus
- 20-minute short break
- 40-minute long break
- Long break after every 2 focus sessions
Why practise at the length of the real paper
The Korean CSAT — the Suneung — runs to fixed section lengths: 80 minutes for Korean, 100 for mathematics, 70 for English. If every practice session you have ever done was 25 minutes long, the first time you sit still for 80 straight minutes will be on exam day, and the collapse in the final twenty minutes will be news to you.
As the exam approaches, matching your sessions to the real paper stops being pedantic and starts being the point: holding attention for a full section is itself the skill under test. This preset is set to the Korean-language paper; switch the focus length to 100 or 70 in the settings when you drill the other sections.
Change the split as the year progresses
While you are still building knowledge, 80-minute blocks are wasteful. Use 40 or 50-minute sessions for lectures and problem sets, and switch to exam-length sessions once you move on to full papers.
At weekends, run the actual exam timetable — first paper at the real start time, real gaps between sections. You end up rehearsing your energy management, not just your answers.
The twenty minutes between papers
The real gap between CSAT sections is twenty minutes, which is why the short break here is set to twenty. Deciding in advance what you do with it is part of exam preparation, not separate from it.
- Build the habit now of skimming a summary sheet for the next subject during the gap.
- Twenty minutes includes queuing for the toilet and drinking water. It is less generous than it sounds.
- A 40-minute long break lands after two sessions — align it with lunch and the day mirrors exam day.
- Pink noise at low volume helps in a noisy reading room, but run full mock sessions in silence: the exam hall has none.
Switching between sections
Each CSAT section has its own length. This preset is set to the first section, Korean language, at 80 minutes. For the others, change only the focus length in the timer settings. The value is saved for this page alone, so the home page and other presets keep their own settings.
The inquiry subjects run 30 minutes each, which looks short on paper, but on exam day Korean history and two inquiry subjects run back to back inside a single section. Practising them in a row is far closer to the real thing than three separate 30-minute sessions.
- Korean language: 80 minutes. The default on this page.
- Mathematics: 100 minutes. The longest section — holding focus through the final twenty minutes is worth training on its own.
- English: 70 minutes. The listening part comes first, so start full practice runs with listening.
- Korean history and inquiry: 30 minutes per subject. Practise all three back to back.
- Second foreign language / Classical Chinese: 40 minutes. If you sit it, practise in the evening — it is the last section of a long day.
Questions about the CSAT timer
Should all my study be in 80-minute blocks?
No. Concept work goes better in 40 to 50-minute sessions. Save exam-length blocks for full papers and timed practice.
How do I switch to the 100-minute maths paper?
Set the focus length to 100 in the timer settings. It is stored for this page only, so your other presets are untouched.
I cannot use a timer in the exam hall, so what is the point?
The point is not to use it on the day but to internalise the length, so that by the exam you know roughly where you are without checking.
