I recently recommended my sister-in-law to do it. She needs an exam, which costs more than 10 thousand. Comparatively speaking, the cost is moderate and acceptable.
The teacher's teaching level is really good. These lectures are very interesting.
The passing rate is not very clear at present, and we won't know until we finish the exam.
During the consultation, they spoke professionally and felt very rigorous. After signing up, they have irregular supervision and study every week, which is very comprehensive and satisfactory.
