Kosakata IELTS per topik: collocation untuk Writing dan Speaking, dengan contoh kalimat
Kosakata dinilai di kriteria Lexical Resource di Writing dan Speaking, dan sangat menentukan Reading dan Listening.

Cara menghafal yang efektif
Hafal dalam bentuk collocation dan kalimat, bukan kata tunggal dengan terjemahan.
Pilih 10–15 collocation per topik, lalu pakai di esai atau jawaban Speaking minggu itu. Kata yang tidak dipakai cepat hilang.
Kumpulkan dari bacaan. Saat latihan Reading, catat 3 kombinasi kata dari setiap teks.
Jangan memaksakan kata langka. Kata sulit yang dipakai dengan salah menurunkan nilai lebih dari kata sederhana yang tepat.
