Excellent teacher

My son is planning to retake SHSAT this year. Since there are very few prep classes available for 9th graders, we asked Teacher Seunghan to tutor him. He is extremely knowledgeable about the SHSAT; he guides my son through his studies while discussing the specific trends and types of questions likely to appear on the 9th-grade exam. It is very reassuring to know that he is always quick to respond to and resolve any concerns we, as parents, might have. He is also incredibly patient in his teaching, which keeps my son motivated and eager to learn. If you are looking for SHSAT preparation tailored to your child's specific level and pace—rather than a standard group class—I highly recommend him!

Proficient and productive tutor.

I strongly like Mr. Seunghan's approach to teaching, going over topics thoroughly and making sure I understood everything. He always confirms my understanding of the topic, and goes over it if there are any problems with the subject. He made sure I understood everything, which was really good, improving my overall performance in turn. Generally just a good tutor who will make sure you succeed. Highly recommended.

Alevtina , 31 lessons with Seunghan

The best teacher for SHSAT test

The best teacher, explaining the lesson well, even though English is a second language for my son, Mr. Seunghan explains and simplifies everything perfectly, thank you very much to him

Natia, 7 lessons with Seunghan

Experienced and knowledge

My son had one online lesson with Seunghan for SHSAT prep and it went well. He is very experienced and well versed with the type and level of preparation required to succeed in SHAT.

Parijat , 15 lessons with Seunghan

Knowledgable tutor but difficult to understand

I thought Mr. Seunghan was very knowledgable but he had a strong accent that made it difficult to understand what he was saying. My son had to ask him to repeat what he said many times. It probably takes many lessons to get used to.

Sau, 1 lesson with Seunghan

Instructor is very knowledgeable.

Seunghan N. was really knowledgeable and practical. He was able to teach my son different ways to solve a problem. The downside which is not a problem is that my son learn at a little slow paste and he should have asked questions or asked the instructor to stop so he can process better. One 1 hour wasn't enough unfortunately. Will look into a second session.
