I would rate ZTM 5 stars.I was struggling to find materials needed for learning with hands on project. Then I know about the Zero To Mastery, I like the way they are teaching us with hands on projects and they also included choosing career path option which helped me.
Great courses which make sense and make lead towords work.
One year ago I decided to start a journey to become a Macuine Learning engineer. I was taking random video courses but still felt lost and I almost gave up. Then I someone gave me a folder containing the AI/ML masterclass from ZeroToMastery and in a short time I started gaining true knowledge and a solid foundation about Machine Learning. I'm living in Haiti(small country in the Caribbean) and actually I can't afford to pay the fees to become a ZeroToMastery member but I would like to. I'm convinced with the kind of courses of ZeroToMastery I can achieve my goal and shift from a simple professional to a great AI/Machine Learning engineer.
Zero To Mastery has been one of the best investments I've made in my learning journey. The courses are practical, up-to-date, and focused on building real-world skills rather than just theory. What I appreciate most is the emphasis on hands-on projects, which helped me gain confidence in applying what I learned to actual software development and AI projects. The instructors explain complex topics clearly, and the community on Discord is incredibly supportive. Whenever I got stuck, I could find guidance from both mentors and fellow students. Since joining ZTM, I've significantly improved my software engineering skills, expanded into AI, cloud computing, and modern development tools, and become much more confident tackling professional projects. I highly recommend Zero To Mastery to anyone serious about advancing their tech career.
I've taken several online courses over the years, and Zero to Mastery has been one of the best learning platforms I've used. The instructors do a great job of explaining not just how to do things, but also why they work. The courses are well structured, hands-on, and kept up to date, especially the AI content. I also really appreciate the supportive Discord community, where it's easy to ask questions, get help, and connect with other learners. If you're serious about building real tech skills, I highly recommend Zero to Mastery.
I’ve had a great experience with ZTM. What stands out most is how up to date their courses are. The content is regularly refreshed to reflect the latest technologies, industry trends, and best practices, which makes the learning experience highly relevant and practical. The instructors do an excellent job of covering modern tools, frameworks, and real-world workflows that are actually being used in the industry today. Rather than focusing on outdated concepts, ZTM consistently delivers courses on topics that are in demand and aligned with current market needs. The lessons are well-structured, engaging, and designed to help learners build skills that can be applied immediately. If you’re looking for a platform that stays current with evolving technology and provides relevant, high-quality education, I highly recommend ZTM.
I have been following ZTM, Andrei and his his team's work for a while now. I first discovered the couses on Udemy and eventually he created ZTM, a stand alone platform for basically ANY coding course you might be interested in. His couses are great if you are planning on advancing your coding career or even just starting out completely new. They regularly update and upload new content relevant to the current age and market. The courses breaks down every aspect of coding so plainly and simply that anyone can understand, better yet, he explains how everything is connected to truly pull you into his amazing work of coding, programming and all things tech related. Most recently I emailed to ask for career guidance and they emailed back the same day to offer personalized advise and information.
I have learnt alot, the way they're explained you never experienced in your life.
I have been learning about cybersecurity through this platform, and it has been incredibly useful. The content is practical, easy to follow, and highly relevant to real-world scenarios. I truly appreciate the structured approach and the hands-on exercises that make complex topics easier to understand. I highly recommend this platform to anyone who wants to strengthen their cybersecurity knowledge and skills. It’s a valuable resource for both beginners and professionals looking to grow in the field.
I really need this. I see a great curriculum, but I can't afford either of your courses. The curriculum and everything are extremely good and one of the best in the world. Thank You
I had been looking for a learning platform that goes beyond boring theory and actually provides practical, real-world experience, and ZTM completely exceeded my expectations. What I appreciate most is their direct, hands-on approach. Instead of getting stuck in "tutorial hell," you are immediately put to work on real projects. The courses helped me bridge the gap between UI/UX design and front-end development, giving me the exact tools I needed to confidently build and structure functional, responsive single-page applications (SPAs) from scratch. The community is incredibly supportive, and the instructors are always keeping the material updated with the latest industry standards. If you want a platform that cuts out the noise and gives you solid skills you can immediately apply to your own projects, I can't recommend Zero To Mastery enough. Truly a 5-star experience!
It was wonderful, it helped me improve for a decent time until the fee got too much to handle
Good Good Good
I recently completed the Complete Ethical Hacking Bootcamp from Zero To Mastery (ZTM), and it has been a genuinely valuable part of my cybersecurity learning journey. I chose this course because I wanted more than theoretical knowledge. I was looking for structured, practical training that would help me develop skills I could apply in real-world scenarios. The bootcamp met those expectations by combining clear explanations with hands-on exercises that reinforced each topic. Throughout the course, I gained a stronger understanding of ethical hacking methodologies, reconnaissance, vulnerability assessment, web application security, and penetration testing concepts. The practical labs helped me connect theory with application, making it easier to understand how these techniques fit into a professional cybersecurity workflow. The instructors presented complex topics in a clear and organized way, and the course structure made it easy to build on previous lessons without feeling overwhelmed. I also appreciated that the content felt current and focused on developing practical skills rather than simply preparing students to complete a course. My overall experience with ZTM has been very positive. The platform was easy to use, the learning materials were well organized, and the quality of instruction remained consistent throughout the bootcamp. If I could suggest one improvement, it would be to continue adding even more advanced hands-on labs and real-world case studies as the cybersecurity landscape evolves. That would make an already strong course even more valuable. Overall, I highly recommend Zero To Mastery to anyone looking for practical, well-structured, and career-focused cybersecurity education. Completing this bootcamp has strengthened both my technical knowledge and my confidence to continue developing my skills in the field.
Zero to Mastery has the right approach to Machine Learning and AI training. There is a clear insistence on practicability in the classes and not just simple content delivery. I particularly enjoyed the Introduction to AI and Machine Learning course, as well as the Data Science roadmap. This is a very impactful online academy and I would recommend it for everyone.
ZTM helped me during the initial stages of my development career, I have purchasing their course ever since when I was in 8th grade. Now in my second year of University I'm working as Mid-Level SWE making ERPS/SAAS products for larger corporations. Really grateful to ZTM for their easy to digest courses that even a 8th grade could understand.
Shout out to Andrei and his team! Their courses are awesome, not only have I learned things that I can apply to my professional life, but my personal life as well! I want to thank everyone who had a hand in these courses as they’re interesting, interactive, fun, and push you to want to Not only to learn more….. but to be more ! I do believe you’re one skill away from changing your life. This ZTM is life changing if you apply what they teach you !
The instructors are excellent and get straight to the point. The quality of their explanations is far superior to any other courses I have taken. I have truly loved the learning experience!
I had chosen ZtM after thoughtful consideration and research. I didn't regret my choice. Having been a full-stack developer for many years, after some time had passed since I left my job, I found the right path to get back in touch. Even if I haven't found a job, the ZtM full-stack developer path gave me a great insight into what is important to know nowadays in JavaScript Full Stack, while the structure of the path gives you the right guidance on how to succeed in it. Even though some materials needed updates, in general, it was crucial to gain the big picture. But updates are really needed to all courses of the path due to past configurations and even more now in the AI era. Extremely valuable were courses like Learning to Learn and the setting goals courses, etc., and some other very important ones, like the Career Guide. Everything is set to give you the best possible chance of finding a developer's job. I have to admit that the timeline to complete these paths is higher than expected, even if you study them full-time. So keep also this in mind, that these timelines apply to full-time study. Being in the step of job searching, I can say that till now, almost all the requirements that I have encountered in job postings and interviews have been covered through the path's material. They made me a much better developer than I was, but that was the basis, and much more work needs to be done to find a decent dev job. More expertise is needed through developing your own applications and gaining the highest expertise through coding challenges. Paying something less than 300€ for an annual subscription and gaining such practical knowledge that not even my university gave me, YES, I suggest from my heart Zero to Mastery platform, at least for the Full Stack developer path, including the ZtM fundamental courses, which make you a better person. Great value for money, but I will mention again that this is the base to put yourself in front of the market, not necessarily that you will find a job even though soon.
Hey Wu - thanks for the review. We're constantly updating or courses and lectures. If there are certain lessons or sections you've found need updating for some reason, please send an email to support so that we can look into it and if need be, work with the instructor to make the necessary updates! Wishing you all the best on the job hunt. Keep working hard and we're sure you're going to make it happen.
Honestly, I love learning on Zero to Mastery platform one of the course I love is complete React course I thought I have seen it all until I put in again for Build AI Agent with N8n Wow the course blown my mind now I can 100% call myself an AI Automation Specialist with n8n that I learnt from ZTM, I have built at least 4 working Automation now, AI-powered LinkedIn Outreach System, Domain Lead Prospect agent and currently I am building another robust AI agent on domain appraisel and acquisitions. Zero to Mastery has really shaping my life to good from nothing to something. Thanks for innovating this kind of platform never seeing is similitude before.
