Final Time Attack Program 16th cohortis starting! The 16th cohort begins on August 20th. Let's start after enjoying the holidays 😊😊 Since the number of participants has been gradually decreasing, I've decided to make this the last one due to the management burden. From now on, I'm planning to try using Inflearn's challenge lecture feature.
This is a program for those who have purchased courses but never manage to finish them. You can participate for free, and for those who lack willpower, we also operate a separate deposit system. You can study by looking at study notes from previous cohorts or current cohort members, and you can also ask questions to me or other participants.
Those who participated in the time attack had a much higher completion rate. If you're truly determined to complete the course, participating will be very helpful!
By the way, rather than searching for me on Inflearn to purchase the course, https://www.zerocho.com/lecture please click this link to purchase, as it significantly reduces the commission fees I have to pay. Please help me out 😊😊
The next upcoming course is a Slack front-end course renewal (Supabase).
Upon completion, we offer course coupons (35~70%, depending on course length) or meal vouchers for in-person meetings (when participating with a deposit)!
I'm also currently running most of my cohorts at a loss. The reason I continue despite this is because I hope my courses will genuinely help all of you. Many people purchase courses but never actually take them, so I run these programs every time hoping that you'll follow the set curriculum to the end and improve your development skills. I feel most proud when I hear that my courses have been helpful. I also make gradual improvements to the courses based on feedback from the time attack sessions, which helps me as well.
Since it's conducted on Slack, you need to join the Slack room. Please enter through the Slack link below.
When you enter, there is a 16th cohort participation survey (Google Form) in the announcement channel. Please fill it out. I'll also post the link separately.
https://forms.gle/GephR8f3jf4ajdre9Even if you haven't filled out the survey, you can still participate by sending me a DM to let me know.
Even if you don't participate in the time attack program, joining the Slack channel will be helpful in many ways as we share information like geek news, answer programming questions, and provide advice and consultation. We already have about 3,800 members!
Thank you.
It's already April of 2025 😭😭 How does time go by so fast...
The 14th Time Attack Program is underway! The 14th session begins on April 14th.
This program is for those who have purchased the course but cannot finish it . You can participate for free , and there is a separate deposit system for those who lack willpower. You can study by looking at the notes of previous or same-age students, and you can ask questions to me or others.
The completion rate for those who participated in the time attack was much higher . If you are truly determined to complete the course, participating will be of great help!
By the way, if you purchase the lecture by clicking on the link https://www.zerocho.com/lecture instead of searching for me on Inflearn, my commission will be greatly reduced. Please help me 😊😊
The next lectures scheduled for release are the renewal of the Slack Front lecture and the renewal of the Delivery App lecture (React Native -> Expo).
If you complete the course, you will receive a course coupon (35-60%, depending on the length of the course) or a meal voucher (if you participate with a deposit)!
I am also currently running at a deficit every term. It is already the 12th term... The reason I'm still doing it is because I hope my course will actually be helpful to you. There are many people who buy the course but don't listen to it, but I'm always doing it because I want you to listen to it all the way through with the set progress and improve your development skills. I feel most proud when I hear that my course was helpful. I'm also helping myself by slightly modifying the course based on the course feedback from Time Attack.
Since this will be held in Slack , you will need to join the Slack room. Please enter through the Slack link below.
When you log in, there is a 13th participation survey (Google Form) in the notice channel . You can fill it out. I will also upload the link separately.
https://inf.run/fSfmyEven if you didn't fill out the survey, you can still participate by sending me a DM and letting me know.
Even if you don't participate in the time attack program, you can join the Slack room to share information such as geek news, ask programming questions , and get advice on your concerns . It will be helpful in many ways. You've already been in for about 3,800 minutes!
thank you
Hello. Sorry for sending you news again.
Last time, I checked that the Zerocho School Slack link was broken and fixed it. I also added Next 15 lectures to Time Attack (fixed from Next 14).
This alone is not enough to send you news, so I'd like to give you some more information.
The lectures that will be released this year are the renewal of the React Basics course, the renewal of the React Native course, the renewal of the Node24 version, and the renewal of the Nest.js course. The Node24 version and Nest.js will also be released as books.
Today, I will be filming a video on YouTube Live about the 2025 developer roadmap, the React stack, and developers in the AI era. I will also be holding a Q&A session with the counseling center. Please show lots of interest.
happy new year
thank you
Zero second dream.
