Harkirat cohort is way way way better than anyother course. Because you learn a lot , infact you learn more than the syllabus given. If you wanna learn , it will be like an individual coach. Polls, interaction, TA, offline videos etc . Just tto make you things clear...i really appreciate....thanks brdr ❤
Bro if i buy 0-100 cohort today will i able cover the syllabus like 0-1 and 1-100 all together ? Bcz 0-1 has already covered, classes of 1-100 will start from 20th April So there would be no live class of of 0-1 suggest me regarding this query

I never would have realized that the Harkirat cohort is more valuable than I imagined. I have to buy this, the price is really justified, I wasted 6lac in engineering just to get this shitty job. All I needed was a teacher like you.
Hey, I think your course is great, but I have a suggestion. It would be beneficial to introduce a learning system that includes repetition of building projects and logic building sessions. This would enable people to develop a thinking mindset and the ability to break down problems into smaller, manageable chunks. Without this, purchasing countless courses may not be of much use.
about that question asked in interview he's considering that what if backend fail in 2nd and 3rd option and its okay you can revert back , what you want as the user that new feature in the website you visiting added after few minutes or the existing feature takes 10 sec more to load ,In 2-3 seconds the load on you website get reduced a lot , generally you don't clear the cache , what if youtube or big companies clear there cache ,that's why it's not recommended
I wanted to get the course from the start but i couldn't buy for some reasons . I'm really waiting for web3 cohort so for that what are the prerequisites?? It would be easier to understand when cohort starts ❤.
hi, I want to make simple score update apo where i will use websocket api to send message(json format) and this will update the score. kindly suggest any simple method or paltform.
Hey Harkirat, I just bought your cohort 2 (0-100) yesterday. I am facing 2 issues. 1. First, I am not able to join Discord with the provided link it directs me to a different page. 2. Second, I have bought (0-100) but in the content I only get to see the (0-1) content then where is the (1-100) content of the course?????? please help me out
hello sir , i am a student currently in 6th semester. I am having a doubt about your cohort course.please let me know whether i should join your course or not as i am currently doing dsa and nothing else and struggling to find internship and also placement season is going to start after some months for which i think i am not prepared.So can you advice me whether this cohort will be helpful for me and also let me know whether there are any prerequsites that are required?
@Harkirat I have purchased the 0-100 course, I am not able to see this video in the course, is it just demo? Will I get any notifications on when the next live class will be? I didn't get any notification for this class
i just want to know wether a beginner can follow 0 to 100 course without any prerequisite or is there any prerequisite to get our hands on before starting the course?
Hi Harkirat! Just finished off this video. Great Insights. I have a Question at 1:45:15 you said that inside a websocket connection we can send the data packets through UDP. And for web socket connection we first do http connection. So how can we have UDP inside HTTP?
Can anyone say when the course will start and will it b like weekly updates of lectures and assignments or just recordings and assignments of all at once

If I buy 0-100 now, will the recordings of all the live classes also be available from 0-1 cohort? 2. Will the 0-100 cohort remain accessible for the next 3 years or 2 years from the date of purchase?
