There are many channels teaches coding and tech stacks, very few teaches where to use those skills and very few really shows the opportunities to solve real life problems. Kirat bhai GOAT for reason.

That's what makes him different than others.

NTA can't afford engineers like you 😂😂

Number of Questions and Sets:
180 universities each provide 20 questions, totaling 3600 questions.
There are 190 ^ 180 possible sets of 180 questions.

Probability of Leak:
If one university leaks 20 questions, the probability that a student gets at least one leaked question is approximately
1− (1 − 20 / 3600) ^ 180.
If all universities leak 20 questions, the probability increases but is still very low.

Probability of Same Set:
The probability that a person sitting around you (left, right, front, back) has the exact same set is negligible, practically zero.

Probability of Overlap:
The maximum possible overlap between your set and the sets of people around you is 8 questions, assuming a highly contrived scenario.

People complaining
Harkirat Fixing 🤣🤣🤣

[arpitgoyal]

harkirat picks up the police cap and takes matter in his own hands. Amazing videos love your videos

[singhiskingdfthdfhgs]

What an intro sirji, hard editing skills🔥🔥🔥🔥

[AshmitSinha]

Thanks a lot man.. U got me so interested in CS by this video.. Also this is absolute bullet proof process.. No ghapla s will take place anymore by this process...👍

[dhruvabhattacharya]

we can shuffle all question no. randomly to prevent some sought of cheating

[kuldeepchhetri]

We need more people like Harkirat in India.

[swastikchattopadhyayc]

Really great content as a Whole .. Mind-blowing

[hirengajjar]

Can we build something to prevent the intentional leak of exam papers? My idea involves dividing questions into categories based on difficulty, from easy to most difficult. Each question paper setter would be required to submit a certain number of questions for each category. Given that we have many teachers capable of this task, the number of people creating questions at each level should be relatively high.

Once all the questions are submitted, a decentralized system would be used to randomly select a set of questions from each category to create multiple question papers. Exam centers would only have access to these machine-generated sets of questions shortly before the examination time.

The overall goal is to minimize human interaction at each stage, ensuring that even the paper setters are unaware of whether their questions will be included in the final paper or not. This approach should help prevent intentional leaks of exam papers.
One notable example is the use of blockchain technology by the Punjab State Aids Control Society (PSACS)

Why does it feels like a movie trailer,

[ArrytroLovesMangoes]

Ig, that Cheating wala problem kindof has a solution existing: Adjacent sitting students are having different sets of questions, which meansthat the order is different or maybe question's pattern is same, but the values are different amd in an environment as big as these competitive exams, the minds3t of one does not help them indulge in verifying amd stuffs..so cheating kindof has been eliminated, although not fully but maybe a bit.

[JainNamit]

Hi Harkirat,
Its always fun and knowledgeable to watch your videos, I have one question for the last part of the video, public key cryptography.
How would be private keys will be shared to user or result calculator in the end to calculate result?

[himanshugupta]

Will there be any cohort 3 or should i buy 2.0

[danish]

This time i am going to download this. for safe side

[lenovoxcarbon]

Bro just want to ask one question plz answer. How do u know all this stuff just by experience or do u study some technical books and stuff

[Triple]

You can't change the system. The system is broken. A new system must be there to replace it.
