USABO (Semifinalist)

Beckman High School 11th

"Hello, I just wanted to thank you for supporting us throughout these past couple months. The exam wasn’t too bad and I think it is in large part due to your enormous help. Please keep teaching other students as your class didn’t just help me with Biology, but I also really enjoyed listening to your stories. I will make sure to let you know of my score once it comes out. Once again thank you so much!"

"I really loved and appreciated the teacher’s thorough, detailed, and clear explanations and lectures. He’s very knowledgeable and passionate in what he teaches and was very crucial to my success in both math and biology. Definitely recommend!"

USABO (Semifinalist)

OCSA 10th

"The lectures are very comprehensive, and it’s incredibly helpful how Teacher John would point out the most important details to remember, since there’s already so much to memorize for USABO. He definitely has an expert understanding of what the exams like to focus on, and things to watch out for. Although the class has to move quickly, I think everyone could keep up thanks to how Teacher John would make sure we understood new concepts before moving on. I think the class is very personalized to our capabilities/needs. Additionally, I really appreciate how he welcomed and answered any and all questions. I can feel that he really enjoys teaching biology and wants all of us to succeed. In my opinion, this class is the best to prepare for the USABO exam."

Troy High School 11th

"For the last 3 years, I've been a student of Mr. Kim, and his classes were the best classes I've had. Whether I was in a one-on-one tutoring class or a group class, I could feel Mr. Kim's dedication to his students. He always made sure I or my classmates understood everything thoroughly before moving on, and I loved the fact that he encouraged students to participate more, because we won't learn by just listening to lectures. His interactive class style stood out from other teachers, and it resulted in great knowledge retention. I'm extremely grateful for having such a qualified teacher as Mr. Kim, and I hope other students can receive his help to become better students."

AMC 10, USABO 101

Hickman High School 9th Gayeong

"As a student who took both Mathematics and Biology classes from STEM & ROOTS Academy, it was an eye-opening experience which I really recommend. The studying materials were really helpful and well structured, detailed and thorough explanation gave me an ambition to study in STEM field. The teaching touches upon 'why' and 'how', and not just simple memorization. During the lectures, the teacher constantly asks questions for students to develop their own ideas and thinking skills which had me studying in my personal time. I could truly feel that the teacher had a great passion teaching students with great skills. Of course, it wouldn't be easy journey studying, but they really do try their best to help students along their way. So technically for any students who are interested, I recommend STEM & ROOTS Academy as your team!"

USABO (Honorable Mention-Top 20%)

Thomas Jefferson High School for Science and Tech 9th

"Before taking USABO 101, I had no knowledge of biology and oftentimes didn’t have any passion to pursue a career in the natural science field. However, taking classes here at STEM & ROOT every Sunday helped realize how amazing biology was. Mr. Kim taught every class passionately and as if what he was teaching was the most important thing there was. Whenever I would ask a question he would not only answer it, but would give the deeper reasoning behind everything. Mr. Kim would make sure that everyone would understand the content and always made it so that we left the class with something valuable each day. I’m so thankful for the endless support and encouragement that I received from my time here at STEM & ROOT."

Crean Lutheran High School 12th Elias

(Vanderbilt University)

"I've had one of the best learning experiences that I couldn't have at anywhere else at STEM & ROOT Academy. If you are interested in focusing on STEM subjects and you want to learn them in-depth, this is your opportunity to do so at this place. The instructor clearly has a purpose for everyone to succeed, learn the materials, and love the subject. He genuinely cares about his students and he is very engaging and open to questions and feedback. Aside from Olympiads and AMCs, when I was in high school, I came across this academy in the summer to prepare for AP Chemistry and AP Calculus AB along with SAT II Math Subject Test. The learning materials were well-organized, with content presented in a logical manner. The instructor did an excellent job of extracting only the core, pivotal concepts I needed to know, which I really liked. After I've done much practice and have taken several simulation tests, I was able to receive a perfect score on both the SAT II Math Subject Test and SAT I math sections. I was also able to boost my GPA with my AP Chem. and AP Calc. AB grades with minimal stress during my first-semester senior year. This fall 2020, I will be attending Vanderbilt University as a music and biochemistry double-major, and I truly believe that STEM & ROOT Academy has given me the confidence and the knowledge that I need in order to bring myself up to this point. Overall, I highly recommend that you check out this academy. Trust me, you won't regret it once you get the hang of it."

AMC 8, USABO 101

Sycamore Canyon School 8th

"10/10. Would recomend. Thanks to the Amc 8 class, I got full marks on my first Moems1 test! The classes are so unique; the teacher goes into full detail of everything and has answers for every question imaginable! A true gem compared to any other class I've taken before!"

USABO 101 (Certificate of Merit)

USABO 201 (Semifinalist)

Lexington High School 10th Juhyeong

(UCLA, Biology)

"From the lessons of USABO 101, it was much easier for me to get a 5 in the AP exam and also get an A in the AP bio class. And although I did not make semifinals for USABO, I did get a Certificate of Merit from 2022 USABO Open Exam. In the class, the teacher goes over things in well detail and order, and personally, after studying and digesting my notes I took during the class, I could answer a lot of questions in my AP bio class in school. The class is a great way to learn AP bio and many different parts of the content of USABO."

AMC 8 (Honor Roll, Top 2.5%)

Beatty Middle School 6th

"I am taking an AMC 8 class. The classes are amazing, and I have enjoyed them immensely. Because Mr. Kim makes the subject extremely easy to understand. The way he teaches gives us the chance to work independently for a little bit, and he gives us hints and ways to solve the problem if we can't understand. I also like how convenient the way of posting and working on homework using Google Classroom, and how the live zoom classes seem like in-person classes. Also, the teacher explains why studying competition math is important for me, so I can develop motivation and passion for this class. Overall, I genuinely like this program and how it operates. I highly recommend this class!"

Brea Olinda High School 11th Grace

(UCR)

“Hello! My name is Grace Lee. I go to Brea Olinda High school and is currently in my junior year. I’m taking 4 AP classes this year and took tutor from John teacher on AP Bio and AP Calc AB. Before going to Stem & Root, I went to several other tutoring places but it didn’t help me as much as it did from Stem & Root. Usually it is really hard for tutor teachers to go in depth with the subject because there is not a lot of time but even with the little time, John teacher tries to tell you everything he knows about it and goes really like really in depth with the subject which surely helps especially for AP classes. He also gives you multiple choice questions and practice test for homework to help you out on AP testing. John teacher not even helped my grade but he also became my mentor and a counselor. He put on effort and time to my works and gave me the best he could. I know the price could burden some of you but I honestly think it is worth it. Hopefully this helped you to know more about stem root:) Thank you!”

AP Biology, USABO

Clark High School 10th

"This is one of the best tutorials I have taken. When going to my first day at this tutorial session for Biology, I have learned a lot. Some of the biology units I have covered at school was recovered during my 1 session but I was able to learn way more in depth. On my first day, one big unit we covered was on the endocrine system. Before going into this trial session I only knew the basics including the endocrine system is many glands that produce hormones for cell communication. After taking this class, I was able to lesrn more than the basics. Not only did we cover some of the basics but covered all the major and minor parts of the endocrine system including the hypothalamus, pineal gland, etc. I would definitely recommend taking tutor classes at STEM & ROOT Academy as just from one class you can learn way more than you already knew."

"STEM & ROOT Academy 를 벌써 1년정도 수학이랑 과학수업을 받았는데 너무 너무 좋았습니다! 제가 영어가 부족해서 다른 학원을 다닐때 가끔 이해하는데 어려운 부분이 있었는데 한국말 영어 둘다 잘하셔서 저에게는 너무 좋은학원이었고, 또 과학 같은 경우에는 가르키는 학원이 별로 없어서 매번 혼자 공부했었는데 John 선생님께서 수학과 또 과학도 모든 수업을 다 잘 가르키셔서 성적도 많이 오르고 많은것을 배운것 같습니다. 제가 못 알아들었을 때면 몇번이고 다시 설명해주시고 또 까먹었을때에도 친절히 잘가르쳐 주셨습니다. 또 여러가지 과목을 잘 가르치시니 때론 시간이 남았을때 다른 과목 수업 질문도 하고 배울수있어서 시간 배분이 잘됐었습니다. 그리고 John 선생님 께서 너무 착하시고 또 수업외에 학생들에게 좋은 조언들을 많이 해주셔서 공부쪽만이 아닌 지식도 많이 쌓고 또 마음쪽으로도 많이 위로 받고, 의지했습니다! 수업도 하나 하나 천천히 잘 가르켜 주셨고 SAT 수업 받을때에도 단순히 test만 풀고 공부하는것이 아닌, algebra 1 부터 calculus 까지 하나 하나 다 배워 SAT문제 풀때에도 많은 도움이 되었습니다. John 쌤과 상담 쌤께 정말 너무 너무 감사드립니다!"

Hickman High School 10th

"안녕하세요 선생님!

지난 1년 반 정도의 시간동안 너무 감사했습니다. 처음에는 정말 아무것도 모른 채 시작했는데 선생님 덕분에 제가 좋아하는 진로도 찾고, 새로운 것들도 많이 알게 되어서 굉징히 의미있는 시간이였어요. 수업이 끝나고 감사하다고 말하고 싶었는데, 못하는 바람에 이렇게 이메일로라도 말씀드려요..! 앞으로도 이렇게 열심히 무언가를 배우고 흥미를 가져본 시간들이 쭉 저에게도 큰 동기부여가 될 것 같아요. 저도 남은 일주일 동안 열심히 해보겠습니다! 응원 부탁 드려요. 그동안 수고 많으셨고 정말 감사드립니다. 좋은 밤 되세요.😊"
