Hi. Starting from August, I'm organizing CF problem-solving classes — weekly 1.5h lessons with heavy focus on homework (pre-assigned problems). It should be suitable for people with rating 1100-2400, but perfect for rating 1300-2300 (so that you would always get a few interesting problems at your level).
There'll be a private Discord server and a CF group with gym mashups and monthly leaderboards. Every week, I choose nice old CF problems (at least 6 per group), usually from 5+ years ago. You get 5-6 days to solve them. The idea is that you should struggle with the problems. A day before a lesson, you vote on Discord which problems you want to see covered. During a lesson, we discuss the solutions and the intuition, but also: wrong ideas, follow-ups, related problems. You can and should ask questions. I won't waste time on live coding, especially in the hard group.
Easy group: problem difficulty 1400-2000, Mondays 15:30-17:00 CEST. First class: 4.08
Hard group: problem difficulty 2100-2700, Tuesdays 15:30-17:00 CEST. First class: 5.08
Very hard group: Let me know if you're interested in a 2800+ difficulty group. I will start one if there are enough people. Though this group would be very time-consuming for me to prepare every week.
Price I: 100€ per month (or 8000 INR for India, 20% off). You get access to everything but need to choose which group classes to attend. Payment link: https://buy.stripe.com/7sYcN71jzb8BdXa4jX6wE0a (You should see the price in EUR/USD/INR/PLN, depending on your country.)
Price II: 50€ per month (or 4000 INR for India). You join the server, get access to recordings and problems from both groups. You don't attend classes, can't vote on problems, and you're not in the CF group leaderboard. https://buy.stripe.com/14A5kFe6lekN4mAbMp6wE0d
If you register until Saturday (2.08), you get a 12% discount with code IOI. You keep the discount forever if you pay monthly/quarterly.
LeetCode / interview prep: I'm also going to do similar classes with Leetcode problems, same time of day. The price will be 150€/12000INR per month (or 75€ without attending the class). If you are interested, you can pay the promo-price 25€ for the first week here. Choose your preferred group difficulty there. If we don't start in August, I will refund you.
Hope you see many of you in the classes. Cheers.
hi, my b-tech in CSE fess is around eur83.33(6000inr) per month. i am from india. i get to attend classes every day (air conditioned). labs for every subject (computer network lab, compiler lab, operating systems lab, unix lab etc). 100eur is too much for me
6000 inr for a indian college is very rare. I think you have applied any caste/income certificate.
bro, state govt college. and i am from general category and have family income> 12lpa, for you info i got 98%in jee mains. haven't you heard about jadavpur university, assam university, jamia millia islamia, iet lucknow etc ( and i am not from any of these university/ colleges).
Arguably, you're overpaying for your classes. University students in Poland pay nothing.
Btw. I understand that there exists free education, and that prices around the world are different. Though I don't think that your example shows an alternative to what I offer. If a LGM with teaching experience starts doing classes similar to mine but way cheaper, then it will indeed be a better deal.
cuz poland is, ofc, the model country
nah brother/sir 100 euro is fine but make sure international transaction convert to native currency as if i do euro transaction forex and other will come in play but 100 euro for such courses is market standard in india for good one one can buy 20-30 euro course of dsa here buts that dont fine skill but the 100 euro are charged for year not month
Sounds like a good opportunity, though class times are hard to make for me at 8:30 AM on a Monday US time.
Hi sir, It'd be more easier to convince our parents for a one time purchase instead of monthly subscription. It's slightly expensive(although thanks for 20% discount)
Hello! Is there any way to pay just once? (For example 400$ for all period or something like this) ?
I want to wait 1+ months to figure out all the details about the classes. I don't want you to pay for a few months and then change some rules after a month (e.g. time of a lesson). Afterwards, I will accept payments for longer periods.
Hi, sounds cool! When will the LeetCode classes be?
Those will start in second half of August, hopefully.
How many people have registered yet? for all the easy hard and very hard category
7 per group (easy and hard) + some for access-only tier. So far only 3 people said they're interested in the very hard (similar for Leetcode classes).
That's criminal. I was doing a similar thing in 2020-2021 in Russian and had more students. I thought you would have upwards of a hundred interested people. The price is very reasonable, I would even say low for a teacher of your calibre.
but having just 4 classes (with that high cost) will always have attraction of very less people I might consider joining if it had more content. I know many would be against me but this is the true point for not many people not enrolling I feel.
In my experience, private tuitions in India cost about the same (although they were 1-on-1). I used to take French tuitions that were ₹5000 per month for just one class a week, so I find Errichto's pricing quite reasonable for Indian students.
It's all relative. I certainly wouldn't bother doing these classes for cheaper than this. Even if I could magically get any number of students, the time spent on just answering questions in Discord would make it not worth it for me (compared to doing any other job, including 1-on-1 classes).
There's now 10 average per group + many students for non-live access. We're getting somewhere.
Also, why are most of your CF comments made under my blogs?
Please make something for coders rated from 800 to 1000 — My dumb brain is not even solving 800 problems of codeforces if you have time please guide
So, I'm assuming recordings will be inaccessible after a month since it's a subscription based model, right? Also, if I subscribe to the course a bit later, will the past recordings and homework problem-sets be available or no?
I haven't decided yet but I think it makes sense to keep the previous 2-3 months as recordings.
Sounds a Very good opportunity,I really want to join it, but the fee is too high for me I can not afford it. Sad, cant join it!

Is there any way to cancel the subscription after 1,2 months?(In case if it will not suit for me)
Yes, there's a Stripe (payment processor) page where you can manage your subscription: cancel, change tier, change card, see date of next payment.
Hey Errichto, We just have to make the payment na nothing more.What is the procedure to join the this.
Hello! I received the Discord invitation for Errichto CP School, but it seems my access hasn’t been approved yet — I still can’t enter the server. Could someone please check or approve my request? Thank you very much for your help, and sorry for the trouble!
PS: If anyone can contact him, please help us!
Same here too, please let me know if you need clarifications on the email for payment that was used!
How much time does it take to for access to be approved as it is approximately 24 hours and it still under review?
It might be helpful. But it's such a pity that it's too late in NZ.

[user:Errichto]Can you add an option for UPI Payment as well?
Is this still available?
can I still enroll in this?
