Fear

what's your biggest fear?
some say darkness, some say ghosts, some say thunderstorms,
or just simply haven't done mathematics assignment.
and so on.

Pengalaman Ikut IELTS Academic

sebulan yang lalu (bahkan lebih), tepatnya 5 november 2016 saya mengikuti international english language testing system (IELTS) yang diadakan oleh IDP Jakarta di gedung pusat pelatihan bahasa ugm. IELTS adalah salah satu syarat wajib bagi setiap orang yang ingin berkuliah di luar negeri, ya TOEFL IBT juga bisa sih, jadi ya pilih sesuai selera sadja.

saya telah membooking tes tersebut jauh-jauh hari dari awal oktober atau malah akhir september, karena takut kehabisan. booking IELTS dilakukan secara online, dan pembayarannya dilakukan melalui transfer atm atau kartu kredit. IELTS yang diadakan oleh IDP tersebut biayanya lumayan juga, 2.75 juta rupiah. jadi, ya harus benar-benar serius dalam mengerjakan tesnya, kalau sampai misalnya di bawah target (di bawah skor minimal admission), ya alamat 3 juta melayang alias mau gak mau harus ngambil lagi untuk daftar ke institusi idaman.

Wish Me Luck on IELTS

hahaha

good night.

tonight was the last meeting of my IELTS course in REAL English. it happened to be a final test, to measure what we students have learnt during the course period. it is just like an IELTS simulation exam. the test consists of listening, reading, writing, and speaking. yeah, we all know that. but this night, we just do the listening sect 3 and 4, speaking, and writing. as reading and listening sect 1 and 2 have been done during the progress test some time ago.

by the way I am taking the official IELTS on November 5, which means about three weeks from now. the test will be held in UKDW. I need band score of 6.0 at least. it will be used to enroll a master's program abroad.

wish me luck.
