Teacher, is it always wrong to use phrasal verbs in IELTS Writing Task 2?

Brilliant question, Chansokol! It is not *always* wrong, as some phrasal verbs don't have perfect single-word equivalents (like "carry out" research). However, replacing common ones (like "look into" -> "investigate") instantly elevates your Lexical Resource score to C1 level. Use Latinate verbs whenever possible in academic writing! 🎓

You technically can, Mina, but it falls into the "Mixed Register Trap"! If you use highly academic words in a casual setting, you will sound robotic, sarcastic, or unnatural. Stick to "also" and "so" with friends! 😂
