The teacher explained Python programming syntax in detail, making programming languages like Python much simpler to understand. With her unique teaching method, there's no need to rely on rote memorization to learn logic effectively. Truly amazing! Highly recommend to anyone interested in learning programming! 🙏 Student Feedback 2 😍 The teacher is incredibly skilled at teaching! I struggled to memorize syntax for programming languages for ages, but Teacher Xu helped me remember 21 syntax formats in just one class! So impressive! I've attended programming classes elsewhere before, but none of them compare to her teaching ability! I highly recommend Teacher Xu! 🙏 Student Feedback 3 😍 Today was my very first experience learning a programming language from scratch, and I chose Teacher Xu's Python programming class. Even though she is Chinese, her English is fluent and professional, which reflects in her teaching. Teacher Xu is incredibly meticulous in her lessons. Not only does she use her own custom-designed materials, but she even writes notes for students during class. She also points out critical syntax details, adjusts lesson content and pace according to learning progress, and creates a relaxed and enjoyable learning atmosphere. For a beginner, I highly recommend Teacher Xu! She also asks about your learning goals before class to tailor the lesson to your needs. 🚩 [Class Essentials] 😎 Preparation: Notebook and handouts provided by the teacher 😎 Class Materials: Systematic materials provided by the teacher at no extra cost 😎 Homework: Small assignments after class to reinforce learning 😎 Supplementary Notes: Additional notes are provided for easy review 😎 Recordings: Class recordings are available for review, so you won't miss out, even in group classes 🔵 Reminders: If you need to cancel or reschedule a class, please notify the teacher at least one day in advance. To protect other students' booking rights, cancellations or changes cannot be made within 12 hours of the scheduled class. Thank you for your understanding and cooperation! 🛑⛔️ Please avoid booking classes during China's early morning hours. ⛔️ 🛑 Available Time Slots: All slots open in the system can be booked directly. 🛑 Extra Time Slots: If the teacher's schedule allows, additional slots can be opened. Please message the teacher to discuss. 🛑 Teacher's Popularity: The earlier you book, the more time slots you’ll have to choose from! 😊 🥰 There are no miracles, only accumulation! ❗️ 🥰 Practice makes perfect! ❗️ 🥰 The best investment is investing in yourself! ❗️
