Here is my testimonial as first time attempt success :
1.This is a four-month marathon and you don't expect to pass simply with 2 weeks' sprint, be mentally and physically prepare for the battle and express class is not recommended.
2.Must do online test after every week's class and ask questions in chat group or to teacher, and record down the key points for revision.
3.Must attend study group. With the help from Jeremy Soh (Pioneer lecturer), we're all inside a whatsapp chat group and we can ask questions and get answers very quickly. I joined study group and meet up every week for revision and all members (4/4) passed the exam one shot.
4. Must attend revision class and this will greatly help on the passing rate.
5. Lastly, I would express my appreciation to Mr. Jeremy Soh, who is the most dedicated lecturer I've seen so far. He shares his own PPT/Summary notes and even give free revision classes. He is the real gem for Pionner.
