🎯 TOEIC Trap: So vs So That
Why “so tired” and “so that he could leave early” are not the same — and how TOEIC quietly checks if you know the difference.
You’re reading a sentence and see “so.”
It feels familiar — easy, even. You pick it quickly.
But the correct answer was “so that.”
That’s how TOEIC gets you.
These two look alike.
They sound alike.
But they do completely different jobs.
So = shows how much or how strong
→ so tired, so fast, so noisySo that = shows purpose or result
→ so that he could rest, so that we wouldn’t forget
🤯 Real TOEIC Logic
TOEIC doesn’t ask you to translate.
It asks:
🧠 Is this sentence about intensity — or intention?
If it’s showing a strong feeling → so
If it’s explaining why someone did something → so that
If you rush, you miss the logic — and the point.

🏁 Final Word: Stop Guessing. Ask “Why?”
This isn’t a vocabulary trap.
It’s a logic test.
Is the sentence showing how strong something is? → so
Is it showing why someone did something? → so that
Check what comes after the blank.
If it has a full subject and verb → probably so that
If it just ends the thought → probably so
That’s it. Fast, clean, unbreakable.
