Btree Code Academy is a great place to learn coding. The curriculum focuses on solving problems rather than just lecturing, and is well designed to adapt to individual student's pace and levels. We were able to customize our learning topics based on our interest and progress. Combined with a small class setting, it feels like having private coding instructions. Our instructor Matthew is very knowledgeable and patient with our young learner. I appreciate the weekly reports about the progress and challenges our student made during each class. Through Matthew, our kiddo learned not just coding, but math concepts and advanced logic. His teaching focuses on exchanging thoughts and ideas with students instead of one-way lecturing. He is transparent, pragmatic, and well-versed in all the coding languages and the programing community that we feel comfortable seeking and relying on his advice regarding areas of opportunity, trending topics, certifications, competitions, or summer camps. The email communication with the school and the owner Daniel is always timely and effective. It's a small and friendly community with like-minded people. Price is reasonable. I highly recommend! read more

We've had a fantastic experience at BTree so far. My son completed their Algorithms program and is now working through USACO-level problems, and the growth we've seen so much growth in the past year. The instructors are highly knowledgeable, communicative, and genuinely attentive to each student's progress. I especially appreciate the thoughtful, constructive feedback provided after every class--it's specific, encouraging, and helps my son understand not just what to improve, but how. Communication has been excellent throughout, and it's clear they truly care about their students' learning and confidence. Highly recommend for students who want to build strong problem-solving and competitive programming skills. read more

We were able to signed up for the summer camp for my 11 year old son this year. He had a blast and looked forward to classes every day. He learned how to create a spaceship game, and Btree sent us a report daily. We had a wonderful experience and would definitely recommend it to anyone who is interested in coding. We look forward to coming back to have more classes! read more

My son had no interest in coding but after attending summer camp at Btree, he is now asking for more classes! He came home very proud of the game he developed and his siblings loved playing it too! The instructor was kind, interactive and genuinely loved teaching the students. They sent progress notes and kept us in the loop of what he was learning frequently. read more

My son has been at BTree for a few months now and really enjoys it. He has learned a lot and progressed through the Python syllabus quite well. Some topics have proven to be quite difficult, but my son has been supported through those and gained confidence from working on solving problems in coding. read more

My 14-year-old son really enjoys this coding academy, where he is currently learning Python. Director (Won Jang Nim) is very dedicated and sincere, and clearly explained the program and philosophy during the trial class. The classes are small, and the Python curriculum is well structured, progressing step by step with regular checks to ensure students truly understand the material. This is not a place where students just show up without learning. The instructors are kind, communication is excellent, and detailed feedback is provided after each class. I would definitely recommend Btree Code Academy. read more

My son has been attending Btree Code Academy for almost 3 years and has made significant growth in his coding skills (Python, game development, logic, and now USACO). I like how they teach the fundamentals and build from there. The instructors are very knowledgeable, patient, and make learning fun. They have very flexible weekday and weekend schedules and reply to messages quickly. Students receive weekly progress reports and get feedback on their progress. I highly recommend Btree! read more

My son has just completed their AI and Machine Learning summer camp, and he absolutely loved it! Same as always, I received the report soon after each class briefing me the activities for the day and how he did. They taught him how to use AI appropriately. He created an AI chatbot, a calculator and was able to train AI to play the 21 game with him perfectly by the end of camp! He was also introduced to machine learning concepts and how they affect AI. My son also excitedly told me his version of class report after each class on the way home without me asking which showed that he enjoyed the class tremendously. After almost two years in which he has completed the Python course and now moving on half way through Algorithms, Btree still manages to keep my son engaged and excited about coding. Great job, Btree Team! read more

My son attended Btree Code Academy here in Irvine since 4th grade and I think it's great. He has learned a lot in the past year he's been going and now is a fan of coding. I sent him here because I want him to become a web/software developer when he grows up and it looks like he is on his way, even though he is many many years away still. The staff members and teachers here are great. Very smart, knowledgeable, and helpful. It feels great when my son comes home and shows me the games that he has built. :) Thank you Btree! read more

My child started attending Btree Code Academy in 6th grade and has been learning for over a year now. He began by creating simple games, and now he is learning Python and building their skills. This academy is a place my child really enjoys; he even wants to go every day, demonstrating how much he love the learning experience. The classes at this academy are not only fun but also designed to effectively enhance students' skills, and both my child and I are extremely satisfied with it. Additionally, the academy regularly sends class reports to parents via email, which detail the child's learning progress and achievements, making it easy to monitor their development. I highly recommend this academy. It will be a great choice for anyone looking to improve their child's coding skills. read more

Truly great place to send your kids to learn coding classes such as Java, Python programming . Teachers are very prompt and email parents the students progress report right after class. Also super easy to arrange any make up classes if you missed classes due to sports etc . I am very impressed with school and would recommend very highly. read more

We explored several coding schools around Irvine, and Btree stood out as the best choice for my son. He's in 8th grade and has been attending Btree for about six months. Since starting, he has made great progress in Python and really enjoys the learning experience. He loves the teachers--they're knowledgeable, friendly, and provide excellent guidance. Plus, the tuition is reasonable. If you're looking for a quality coding program, Btree is definitely worth checking out! read more

My son started with basic Python, has mastered Java, and reached the professional level in less than two years. He is very confident with coding now and competitions. He wants to learn more languages to pass a more advanced level of USACO and develop apps as well. In the beginning, I was concerned about group lessons, but it was like a private lesson because the coach taught everyone individually at their own pace. Also, the coach gives some room for students to try trial and error for self-development. Teachers are very supportive and work hard. I like their weekly feedback notes so I can know exactly where my son is now. Thank you for your hard work and sincere business for Kid's learning development, resulting in outcomes as well. read more

My son has been attending Btree Code Academy for two years, and his logical thinking skills through their coding classes have improved significantly. Their teaching philosophy focuses on encouraging independent thinking rather than spoon-feeding information. He has learned how to break down complex tasks into manageable steps, so now he can solve difficult problems with ease. Currently, he is preparing for the USACO Bronze competition and feels quite confident in his problem-solving abilities using Java. I am so pleased with Btree Code Academy. read more

The best place to learn coding in SoCal. I started almost 5 years ago back when I was a high school freshman to learn about competitive programming and software engineering. BTree turned coding into something that I love, teaching me to build impactful projects, to mature problem solving skills, and inspiring curiosity. I'd never been more passionate for learning until I attended BTree, and I would not be the engineer / student that I am today without Daniel and his team. read more

My 10 years old boy has been attending Btree Code Academy since June 2023, and he absolutely loves going there. It is his second coding school, and his skills have been significantly improved after moving to Btree Code Academy. Btree's coding exercises require lots of logical thinking and problem solving skills, and it has even helped with my son's academic skills as he often struggled with math word problems and reading comprehension. I also appreciate their in-depth summary about my son's progress. Being an engineer myself, I can tell that Btree's python classes are very professionally structured. The curriculum introduces important concepts step by step, and lets the student digest the concept with many examples. Overall, I'm very impressed with Btree Code Academy, and I'm happy to see that my son is building profound foundation for programming. Most importantly, he is still very motivated, and growing his high interest in coding thanks to Btree Code Academy. Highly recommended! read more
