My experience with K21 has been stellar!
With K21, you get what you put in. They have an organized, dedicated, and very responsive team that knows their stuff. If you come with clear goals and are ready to put in the work, K21 would take you from the start to the finish line.
In their AWS for Jobs program, I experienced their commitment to my success right from the top, with Mr. Atul personally invested in answering our questions. The support team was very good and my instructor was knowledgeable (Ameya was the instructor for my batch. I recommend him!)
They provided the resources I needed to succeed, from on-demand videos, to live classes, and interesting labs to solidify what I learnt from the live classes, and timely responses to my questions. In short, they had the tools and resources that I needed to succeed, and I was able to pass the AWS Solutions Architect exam on my first try.
I highly recommend them!

I enrolled in a course with K21Academy on June 16, 2025, with the promise of a 6-month full refund policy if I wasn't satisfied. I attended all 4 live prerequisite classes, completed all available activity labs, as required in their refund terms.
However, when I requested a refund on June 25 (just 9 days after purchase), I was told to complete projects — even though the actual course hasn’t even started yet and projects haven't been made available.
This is extremely unfair. I provided:
My full participation logs
Proof of labs completed
Still, I’m being denied a refund based on requirements that are not possible to meet yet — since the content hasn’t been delivered.
This feels like a violation of their own stated refund policy. I’ve tried to communicate calmly and respectfully with their team but have not received a satisfactory response. As a working professional, I trusted this platform with my hard-earned money, and I’m now extremely disappointed with how this has been handled.
I sincerely hope K21Academy reconsiders and honors its own refund guarantee. Until then, I would advise others to be very cautious and make sure all refund policies are clearly clarified and honored before committing to any course.

Excellent teaching and support! Nice resources...
Howver I felt in Python ML classes student need to work many hours other than class room hours. For example it took 1 week of self study on the NumPy topic, the class room hours on this topic is 3 hours!!!

I'm truly grateful to the entire K21 Academy team for their guidance, mentorship, and unwavering support throughout my journey. Highly recommended for anyone serious about advancing in cloud computing!

I’m beyond excited to share that I’ve successfully earned the Microsoft Certified: Azure AI Engineer Associate certification from Microsoft! This has been a major milestone in my professional journey, and it wouldn’t have been possible without the incredible support and guidance I received from the K21 Academy and their dedicated team.
I enrolled in the AI Job-Oriented Program with the goal of breaking into the Azure AI space, and looking back, it was one of the best decisions I’ve made for my career. The structure of the program, the quality of instruction, and the personalized support truly exceeded my expectations.
🔹 Special Thanks to the K21 Team:
From day one, the entire K21 team has been nothing short of amazing.
Jalal’s lectures were exceptionally clear, insightful, and well-paced. His teaching style made even the most complex AI concepts approachable and practical.
Izhaar, Atisha, and Manish offered constant support throughout the course. Whether I had technical doubts, needed help preparing my resume, or wanted mock interviews and guidance on certification exam questions, they were always there. Their attention to detail and willingness to go the extra mile really made a difference.
What stood out to me the most was how the program wasn’t just about completing lessons—it was about building real, job-ready skills. The hands-on projects, the certification preparation resources, and the interview readiness sessions were instrumental in helping me gain confidence and clarity on my career direction.
Thanks to the collective effort of the K21 team, I was not only able to prepare effectively for the Azure AI certification exam, but also gain a solid foundation in AI and cloud-based solutions that I can now confidently apply in real-world scenarios.
🙏 I’m sincerely thankful to the entire K21 team for their dedication, mentorship, and belief in my journey. Your support has truly helped me transform a goal into an achievement.
🚀 That said, this is only the beginning. I know I have a long way to go in mastering the Azure AI ecosystem and securing the right role in this exciting domain. And I’m confident that with K21’s continued support, guidance, and encouragement, I’ll be ready for every step ahead.
To anyone considering a career in AI or cloud technologies: I wholeheartedly recommend the K21 Academy. They don’t just teach—they partner with you on your journey.
Thank you once again, K21! 🙌

If you are looking to launch a fulfilling and technically skilled career, especially in the cloud, K21Academy is the place to start. My personal journey is a testament to this. I transitioned from a general IT support role to an Azure Cloud Engineer, a transformation entirely powered by K21Academy's program.
The team's depth of knowledge in cloud technologies is remarkable, and the technical support I received, particularly from @Manish and @Atisha, was invaluable – their dedication and patience are truly exceptional. Initially, the Azure Cloud Job-Oriented Program felt overwhelming, but within just two months, I began to see the tangible impact of the training. Six months later, I secured a well-paying position as an Azure Cloud Engineer. I wholeheartedly recommend K21Academy to anyone seeking a significant career change, whether as a short-term boost or a long-term goal.
Thank you to the entire team for this incredible opportunity!

I recently came across K21 Academy’s advertisement on Facebook and attended a free class. When I attended the free session, the primary emphasis was on how their training could lead to a $250K salary and highly paid job opportunities. The entire focus was on selling the idea of high salaries that students would supposedly secure after enrolling in the course. However, they provided no clear explanation of the course content, delivery methods, instructor credentials, or certification details.
For example, when it comes to teaching Microsoft Azure, one would expect a certified instructor with real-world experience in the technology. Unfortunately, none of this was discussed. Instead, the focus remained solely on financial outcomes.
On their website, the course was advertised at $3,000. But when I inquired further about the training details, the salesperson suddenly increased the fee to £6,000, merely because I had shown interest and booked a consultation call. During the call, the salesperson claimed they would assess my suitability and current salary, and confidently stated they could secure me a £160K job—as if they were going to issue the offer letter themselves.
That immediately raised red flags, as £160K is an unusually high salary, typically reserved for senior development managers in London. The next question posed was whether I was ready to pay £5,000 for the course. Yet, no proper information was given regarding the course structure, delivery method, or the qualifications of the instructors—factors that are critical for any technical training program.
Instead, they bombarded me with testimonials from past students and repeated claims that attendees landed $250K jobs after completing the training. To me, the entire business model seems to revolve around enticing students with unrealistic salary promises and instilling false hope, rather than delivering genuine education. It felt more like a marketing scheme than a legitimate training institute.

I sincerely thank K21 Academy for their full support and structure during my Cloud learning journey.
I enrolled in their AWS Certified Solutions Architect and DevOps course, it was a game-changer. The way they break down complex cloud concepts, especially around AWS, DevOps tools, and CI/CD pipelines, helped me build the hands-on experience and confidence I needed.
Special thanks to the instructors Nisha, Swami S, and the Senior Boss Atul and the support team, like Shubhangi, Manish V, who didn’t just teach the theory but guided us through real-world labs, projects, and even helped with interview preparation questions and mock sessions.
I'm happy to share that I just completed a technical phone interview for a Cloud Engineer role, 3rd interview within 2 weeks, everything I learned through K21 played a huge part in helping me get there.
If you’re serious about building a career in cloud or DevOps, I highly recommend K21 Academy, not just as a course, but as a career partner. Keep up the amazing work!

Dear K21 Academy Team,
I wanted to express my heartfelt gratitude for the exceptional support I've received from your team over the past 7 years. Recently, I was preparing for a job interview that required knowledge of Oracle Cloud Infrastructure Observability Professional, which wasn't part of the original course curriculum.
Special thanks to Richa and Manish, who went above and beyond to provide me with valuable guidance and configuration steps, helping me feel more confident and prepared for the interview.
Thank you for your dedication, expertise, and commitment to your students' success. I'm grateful to be a part of the K21 Academy community!
Best regards,
Kunwar Muhammad Zahid Chauhan

I have been enrolled in the K21Academy programme for a few months, and so far, I have found the live classes to be both informative and engaging.
Even when I am unable to attend a live session, there is always the opportunity to catch up through video recordings, accompanied by detailed summaries and well-structured learning materials, rich with documentation and practical labs.
The K21Academy support team has been fantastic throughout—consistently following up with me and other learners, either directly or via dedicated WhatsApp groups. These groups are updated in real time with helpful links, screenshots, reminders, quizzes, and lab files.
I would especially like to thank Manish from the K21Academy support team for providing invaluable support with CV preparation and job interview guidance. The advice I received was methodical, detailed, relevant, and well-organised.
This support went even further, including suggested responses to interview questions tailored to match specific job descriptions. When I shared a job description and interview questions of my own, Manish and the support team responded promptly with highly relevant and practical insights.

Very good. Excellent instructors. I am not sure why there are no live classes for DevOps since we have labs for it. The classes are informative and well-structured. However the timestamps on the live recordings are not always accurate with what’s on the screen.
