Thanks to Saurabh for technical Support!

I would like to extend my very special thanks to Saurabh and Sumti for their outstanding support in resolving my AWS issue.

I had incurred approximately $200 in unexpected AWS charges and was very concerned about how to get them resolved. What stood out the most was that they took complete ownership of my case. They handled the entire process, coordinated with AWS Support, followed up consistently, and ensured the issue was resolved on my behalf.

I was facing this billing issue for the last month but within just 48 hours my AWS issue was resolved and I'm happy that I can finally resume my AWS learning journey and hands-on practice.

I truly appreciate their professionalism, responsiveness, and commitment to helping learners. I highly recommend them to anyone who needs reliable AWS support.

I started the AI/ML Job-Oriented Program with K21Academy about a month ago, and so far, my experience has been very positive. The live classes are engaging and well-structured, and the support team is incredibly prompt at responding to any queries. While it is still a bit too early to give a full 5-star rating since I'm only a month in, I am highly satisfied with the program's direction and momentum so far!

Excellent guidance and support

I wanted to express my special appreciation to Atisha and the team for their constant support throughout my job search and interview preparation journey.

The interview guides Atisha has provided have been invaluable study material and have been remarkably accurate in reflecting the types of questions asked during my interviews. The team’s response and support with interview preparation guides have been amazing.

I would especially like to thank Atisha for the outstanding support she continues to offer. It has made a real difference to my preparation and confidence.

Great Introduction to Azure Cloud Computing

The instructor did a great job of breaking down the basic information in this Introductory Course on Azure Cloud Computing.

He makes sure you know the key concepts required for a basic understanding of material. He also makes sure you know what is important.

I walked away with a clear understanding of the definition of Cloud Computing, the various Deployment Models and associated with Cloud Services common to the various Cloud Vendors.

The instructor also did a great job presenting the material based on his technical knowledge and from his previous experience. He took the time to engage interaction with the class by asking them questions throughout the presentation.

He provided a structured method of presenting the material in each section and allowed for Q & A time at appropriate points and at the end of the class.

I felt that support was always available to me via the Portal and when I had questions specific to my situation, the email group provided was helpful in resolving my questions or concerns within 24 hours.

Overall, I give this course high marks.

​I recently joined K21 Academy and have already spoken with three of their experts: Anjali, Shahid, and Malika.

Everything looks incredibly promising; they are highly supportive, professional, and clearly experts in their fields.

​While there is a substantial amount of informative material to cover, I am confident that by staying dedicated and following the career path Shahid outlined in our last call, I will achieve my professional goals.

​Once I successfully complete the AI/ML course and secure a matching role, I fully intend to return to K21 Academy for further advanced courses, just as Shahid suggested.

My experience with K21 Academy

I enrolled in K21 Academy to develop my skills in AI/ML, and it has proven to be a valuable decision. The instructors are knowledgeable and experienced, and they present concepts in a way that is accessible to learners from diverse backgrounds. The support team is responsive and helpful in addressing queries and resolving issues in a timely manner. Atul sir always provide consistent guidance to all learners from multiple learning tracks. The live classes, online learning materials, and structured lab instructions contributed significantly to my preparation for the Microsoft Azure AI Fundamentals (AI-901) certification exam, which I was able to complete successfully.

# Exceptional Learning Experience with K21 Academy – Successfully Passed AWS Certified AI Practitioner (AIF-C01)

I am delighted to share that I successfully passed the AWS Certified AI Practitioner (AIF-C01) certification exam, and I would like to express my sincere appreciation to K21 Academy for providing an outstanding learning experience throughout my certification journey.

As a technology professional looking to strengthen my understanding of Artificial Intelligence, Machine Learning, and Generative AI on AWS, I evaluated several training providers before choosing K21 Academy. Looking back, it was one of the best decisions I made for my certification preparation.

What impressed me most about K21 Academy was the structured and comprehensive approach to learning. The course curriculum was carefully aligned with the AWS certification objectives and covered all critical domains, including:

• AI and Machine Learning fundamentals
• Generative AI concepts and use cases
• Large Language Models (LLMs) and Foundation Models
• Amazon Bedrock and Generative AI services
• Responsible AI and ethical AI practices
• AWS AI/ML services and their real-world applications
• Security, governance, and operational considerations

The instructors demonstrated exceptional expertise and had a remarkable ability to simplify complex technical concepts. Rather than focusing solely on exam preparation, they emphasized practical understanding and real-world implementation scenarios, which significantly enhanced my learning experience.

The hands-on demonstrations, live sessions, and practical examples were particularly valuable. These sessions helped bridge the gap between theoretical concepts and actual business use cases, making it easier to understand how AWS AI services can be leveraged in enterprise environments.

Another aspect that deserves special recognition is the support ecosystem provided by K21 Academy. The mentors and support staff were highly responsive and consistently willing to help clarify concepts, answer questions, and guide learners through challenging topics. The collaborative learning environment created a strong sense of community among participants.

The practice assessments and exam-focused preparation materials were also extremely beneficial. They helped me identify knowledge gaps, reinforce key concepts, and build confidence before taking the certification exam. By the time I sat for the exam, I felt well-prepared and comfortable with both the technical content and the exam format.

What sets K21 Academy apart is that their training goes beyond helping students pass an exam. The program builds genuine knowledge and practical skills that can be applied immediately in professional environments. The insights I gained regarding Generative AI, Amazon Bedrock, AI governance, and AWS AI services have already proven valuable in expanding my understanding of modern AI solutions.

I highly recommend K21 Academy to anyone preparing for AWS certifications, particularly the AWS Certified AI Practitioner certification. Whether you are an IT professional, data engineer, cloud architect, developer, or someone beginning your AI and cloud learning journey, K21 Academy provides the guidance, resources, and expertise needed to succeed.

Thank you to the entire K21 Academy team for their dedication, professionalism, and commitment to helping learners achieve their goals. I look forward to continuing my learning journey with your future programs.

I highly recommend K21 Academy for AI training. The entire staff is always helpful, approachable, and supportive. The course materials and training sessions are well-structured, practical, and very beneficial for learners at different levels.

What truly sets K21 Academy apart from other training institutes is the way their staff continuously motivates students to learn and succeed. They regularly follow up on each student's progress and genuinely care about their learning journey.

Another outstanding aspect is their responsiveness. If you encounter any issues or have questions, the team typically contacts you within 24 hours and works diligently to resolve them. Their commitment to student success and excellent support make the learning experience exceptional.

Overall, K21 Academy provides high-quality AI training along with outstanding student support, making it an excellent choice for anyone looking to build their AI skills.
