”It’s already my third month joining Istari Class, and so far I really enjoyed it. I have learned about English, especially tenses and grammar. The teacher is always open to questions and explains everything clearly during the class. the interesting is, kadang aku juga ditawari untuk bahas hal hal lain “diluar materi silabus” yg masih jadi concern atau kebingunganku. its really helps for me, karna pemahaman kalimat dengan structur yang berbeda terkadang juga bikin bingung. And because of this class, I’m now more confident in choosing the right words for business emails and speaking in forums or meetings. ya walaupun, kalimat yg ku susun masih belum perfect pas ngomong, but I believe it is all part of the learning process. Overall, this class has helped me improve both my English skills and my confidence.”

”Learning w Istari has been great. Before i signed up, my biggest struggle was literally just trying to understand English. But tbh, after taking their classes, everything had changed n my English has improved so much. The way they explain everthing is super structured and ez to follow. The best part was the interactive discussions.”
