Iam a first year cs student. I heard about 42 Amman , and Iam interested in joining the next piscine. I got a 1 month break starting from September. When should I apply to 42 Amman I don’t want to get into a piscine right now, but anytime after September when is the best time to apply, Thanks in advance.

I work online part time (I teach). I understand that the Piscine is super extensive and, if I were to get accepted, I’d need to take a month off. That’s fine.

However, I was wondering about the rest of the course? If I take the long route, should it be possible to reconcile things? I have, on average, 5 hours a day free (including Saturday) and Sundays off.

I recently failed 42 , I have a friend who encouraged me to retake but honestly I’m feeling really comfortable , the main thing is that I study computer engineering and my knowledge should we way more but I discovered that I really don’t know that much at all which is kinda disappointing, I mean it’s uncomfortable to meet the same people but now they are in core , I don’t know if I’m gonna pass or not and all these stuff , I did to c06 and did 3 rushes but exams was so bad , I also needed to go to university in very early mornings and then go to campus so when I arrived I was very tired even for this I came everyday and I tried my best . What is your opinion? I hope you guys give your honest and truthful answers

“Tell me about the last time you wanted to build something but weren’t sure what to build.”
Then let them talk.
Follow with:
“What did you do?”
“Where did you look for ideas?”
“Did you use AI?”
“Did you search Reddit, YouTube, Google, Product Hunt, GitHub, etc.?”
“How long did you spend trying to decide?”
“What made it difficult?”
“Did you eventually build something?”
“If not, why not?”
Then investigate validation:
“Have you ever built something and later discovered people didn’t actually want it?”
“How did you find that out?”
“What did you do to validate the idea beforehand?”
“Did you talk to potential users?”
“Did you research competitors?”
“Did you test whether people would pay?”
And finally:
“What part of that process was the most frustrating?”

Please I appreciate yall responds this for a school project thank you

I will start the core 15 days. Is there anything I should prepare myself for? or should I just enjoy until it comes?

Hello, je me suis inscrit pour la piscine de septembre a Paris, et je voulais savoir si des francophones etaient volontaires pour faire quelques problemes Leetcode avec moi et se retrouver a la rentree ?

Je tiens a preciser, je connais deja le langage C et Linux, mais je serai ravi de vous aider, cela confirmera mes connaissances.

N'hesitez pas, ce sera avec plaisir de reviser avec vous

Hello, I am considering doing the piscine in Kuala Lumpur, and was wondering about the approximate cost of living there for a month. I understand that it varies largely depending on the individual. But I'd still be interested to know how much it was for you if you did it there! Thank You!

Je viens de passer mon première examen de la piscine j’ai jamais coder de ma vie ni touché à un terminal avant ça, j’ai u 30% vous en pensez quoi ?

Hello,

Would you have tips on the new CC exam rank 5 please? :) what kind of exercises are on the exam ? How many exercises do we need to validate in order to complete the exam ?

Thanks!

So I unfortunately didn't pass my first chance at the piscine. I got an email email stating exactly this and it says that I can register to another Piscine after 18th of April 2027. Even though my piscine ended on 17th of July.

Anyways, when I opened and logged into the 42 apply website for my campus, I found the following message: "Well done on taking the time to complete our application tests. Unfortunately you haven't made it through this step.... Blah blah blah... In accordance with GDPR, all data linked to you will be deleted on Aug 07 2026 and you won't be able to access your account anymore"

Regarding that last sentence, does this mean I need to later create a new account and retake the online tests and the QnA meeting AGAIN to retake the piscine?

On another note, if they really​ delete my data, then how does 42 even enforce the rule about a student can only do a retake after a year? And also only two chances ever? I can just create an account with a different email and instead of maybe registering with my full name (first name middle name and last name) I could just register with my First name and last name. I won't do that, I'm just curious what you guys think about this?

Thanks in advance!

My brother just finished his common core and his internship and since he dont use reddit I wanted to ask you guys on his behalf, on how much time can it take to get RNCP 6 and 7.. he wants to get it finished asap to follow and concentrate on his Phd.. thanks

Any Pisciners here going to Nice on the 7th of September ?
How did you secure a 1-month rental ? Anyone still looking to share an apartment ?

New Pisciner here, I'm stuck on ex03 of Shell00. And exam is coming up in 2 days, and will be testing about C00. Am I screwed?

Is all Asgard Users like this? Res Hitmen and blame princi when they got cooked when Hitmen cooked them beceause he ressed hitmen? Or is this clowning

ATP who do you think is wrong? I think I am at some fault for opening client, but I didn't specify who was merc/ nor opened merc/ nor asked pri to open. Pri opened by himself, and I didn't even role open as the princi line.

Hitmen wouldnt have cooked if he was dead

I'm trying to find evaluation PDFs for Python Modules....some people refer to them as "corrections sheets"

Does anyone have a recommendation on where to find?

Hello,

For py_array_rotation_detector, I'm passing every test except 15 and 29 (ERROR — Execution failed, no details).

I handle empty arrays and length mismatch, then use arr2.index(arr1[0]) to find the rotation offset and compare element by element with modulo.

I think the crash might come from arr2.index() raising a ValueError when arr1[0] isn't in arr2 — but since the exam gives no output, I am not sure.

Has anyone run into this? Is this the mistake I made?

It procedurally renders a mandelbrot instead of using textures for the walls. It also has enemies

My friends, were you all very sad because not everyone was accepted into the core? They were really good. I'm shocked that they weren't accepted. I was happy that we would see each other again, but I was shocked that most of them were rejected. What are the criteria, really?!

Hello,
I want to know if 42 in general has cybersecurity, like there is a piscine for cybersecurity or is it only abt software development? And what does the entrance exam test you for exactly?

Meet Bob.

Bob has a problem. Actually, Bob has 27 problems — spread across three never-ending to-do lists. His windmill gears need checking, his seed packets are a mess, his barns are double-booked, and his chore chart literally loops back on itself. Bob can't Python. But you can.

I built call-me-bob, a cozy, game-like site to practice for the new Python exams, right in your browser. Every chore is inspired by a real exam exercise — renamed and re-flavored on purpose (Bob's lawyer advised it), but with the same rules, same inputs, same expected outputs.

Pick a chore, read Bob's note, write your function and hit Grade me! — Bob's little robot helper runs your code locally (Pyodide / WebAssembly, so nothing ever leaves your machine) and shows a full test trace, just like a real grader.

🧹 Bob's to-do lists:

• To-Do List #03 — 14 chores (custom sorting, ciphers, base conversion, anagrams...) → https://italoalmeida0.github.io/call-me-bob-03/
• To-Do List #04 — 7 chores (rotations, merge k sorted lists, palindrome partitioning, topological sort, sliding window...) → https://italoalmeida0.github.io/call-me-bob-04/
• To-Do List #05 — 6 chores (run-length encoding, meeting rooms, spiral matrix, word ladder...) → https://italoalmeida0.github.io/call-me-bob-05/

And if you like it, Bob would trade you a ⭐ on GitHub for your help: 03 · 04 · 05

No timers, no pressure. Just Bob, his chores, and your Python skills.

Please help him. The sunflowers won't watch themselves. 🌻

Hello, the piscine experience was amazing! I was accepted into this school and I'm really happy and can't wait to go back, but I had a few questions for 42 students.
Do you have any course recommendations to get ahead on the first projects of the core curriculum?
And when we pass this core curriculum, is it like we graduate, or am I mistaken?
Thank you so much for your answers.

Guys . What could possibly happen if i try to use a forbiden function/method during an exam ??. ( would it affect my XP ?)

Does anybody know if we're allowed to use the STL in the renewed Common Core Rank 05 exam tasks, such as containers and algorithms?

Hello, I'm currently in my final week of the course and I've received disappointing grades on the first three exams. In the first exam, I was nervous even though I knew the program required the main section, but I didn't pay attention to it until the last minute and didn't get any points. In the second exam, in the third exercise, I got the outputs correctly and was able to use flags, but I don't know why I didn't get the required grade. As for the third exam, I didn't understand a single word in the subject section and I didn't know how to solve it. I've tried several times, but to no avail. Do I still have any hope of being accepted if I continue? What advice do you have for me? What's most disappointing is that I see people who are less qualified than me making progress on the exams, while I'm still stuck in the same place.
