"I don't even have enough time for Korean, English, and Math, so when on earth am I supposed to study memorization subjects?"

This is a dilemma every middle school student faces. History, science, social studies... there is a mountain of material to memorize, yet nothing remains in your head after the exam. Even the content you painstakingly memorized vanishes surprisingly cleanly after just a few days.

The problem isn't that you are "bad at remembering." It is because the human brain is designed that way.

■ Why do we keep forgetting? — The Ebbinghaus Forgetting Curve

According to research by German psychologist Ebbinghaus, people forget about 70% of what they have memorized within just one day. This means that you can never retain information for long after memorizing it just once.

However, conversely, if you review the material again at "that very moment" when you are likely to forget, your memory strengthens rapidly. If you repeat this process a few times, the content transfers into long-term memory with just a short investment of time, making it difficult to forget. This is the power of "Spaced Repetition," proven by learning science worldwide.

■ Daldal Amgi Calculates Your 'Review Timing' for You

The problem is that it is nearly impossible for students to keep track of that optimal review timing on their own.

Daldal Amgi remembers every single problem you have solved and selects and displays only the "problems you need to solve again right now," based on the forgetting curve. Problems you know well appear less frequently, while problems you keep getting wrong appear more often. This allows you to efficiently memorize only what is absolutely necessary without wasting time.

■ 10 Minutes a Day: Memorization Subjects Now Automatic

You must set aside time to focus on Korean, English, and Math. For memorization subjects, just 10 minutes during your commute to and from school, during breaks, or before bed is enough. Even if you solve just a little bit each day—only the problems selected by Daldal Amgi—the exam scope will automatically accumulate in your mind.
