Schoolhouse.world Debating Series!

    Ended Wed, Dec 31, 2025

This is a debating series, and every day there will be a different and unique topic. 6 learners are selected every session, 3 in affirmative and 3 in negative, to debate their stance on the topic (note: you don't get to choose which side you want to debate for). As being part of the larger upcoming World Scholar's Cup (WSC) preparation series, this debating series would follow the WSC debating format, with 15 minutes of individual topic researching followed with a speaking time of 4 minutes (communication with teammates through Zoom text, both before and during the debate, is allowed). There is a 1-minute preparation time between each speaker. After the debate concludes, [this rubric](https://schoolhouse.world/redirect?code=dZCT2Cu4g1wGiPoXncETs) would be used to gauge the rating of each speaker, with improvement suggestions, if applicable. Learners who were not selected to debate in a session are still welcome to stay and observe the debaters and can also give feedback after the debate. The sign-up limit is set to be higher than 6 due to the fact that not every learner might be available in all sessions. IMPORTANT: Because this is a debating series where voice communication is important, please prepare and ensure that your voice, computer speaker, and internet are good prior to the session (video is optional). We would have to assign you a spectator role if we selected you and you cannot respond using voice as debating cannot be conducted effectively through text. If you wish to be a co-host for the upcoming Schoolhouse.world WSC team, please send a co-host request through this series and DM Yoon Ha H after completing [this form](https://schoolhouse.world/redirect?code=Ei9B94A4-V7eBsiwNluSU). If the form doesn't work or has issues, please complete the [PDF version](https://schoolhouse.world/redirect?code=1mhEnkCzZemXTzkVw0bEb) (in Schoolhouse.world Tutors Slack) by annotating with your responses and sending the completed PDF. Thank you in advance!

Repetitive SAT questions

    Ended Fri, Dec 5, 2025

This course is recommended for those who have an SAT Reading and Writing subscore of 500~700 In this course, we will look at more than 50 SAT Reading and Writing passages that have been repeated throughout multiple SAT tests (yes, the College Board does recycle passages over multiple SAT tests 🤨). Why should you take this course? If you attend the course and take the SAT test, maybe you find a few questions that look similar, except with a few minor parts changing (such as "Malaysia" being replaced with "Phillipines", but everything else is the same). As everybody who has taken the SAT test knows, we always run out of time in the 2nd Reading and Writing module, so we have to solve easy questions quickly and save time for the incredibly difficult questions that take multiple minutes of effort. If you already know the passage, you won't have to read it again to understand the passage - you already have a feel of what it's about. In every session, we will go over around 6~8 passages, most of which discuss about Logical Completion, Underlined Text, Purpose of Text, Text Structure, and so on. The passages will be will be distributed through a Scribd link and used throughout the course. The document was crafted by me and will be distributed a few hours prior to the session through Scribd. Join my session, and you will experience the "Oh wait I remember that text about exaggerated effects!" in the actual SAT test.

Math for the November 2025 SAT

    Saturdays 3:00 PM, Sundays 3:00 PM

Hello! I am Yoon Ha and very interested in helping you succeed in the goals you pursue - an improvement in SAT Math. Through co-operation, I strongly believe that we can achieve the goals we all pursue by sharing our expertise. This four-week tutoring series will help you prepare for your upcoming SAT in Math. By the end of the series, you will have completed multiple practice tests and worked through a number of problems from previous SATs, helping you build confidence for your upcoming exam. You’ll spend each session with me and a small group of other learners who are also working towards taking the SAT. Since it’s a small group, you can expect sessions to be very interactive as you work together towards improving your SAT skills as much as you can! Note: Cameras should be on so we can all get to know each other! If you have a specific reason why you can’t have your camera on, please notify me ahead of time.
