Excellent teaching style and excellent understanding of teaching topics. I like the most about the course is how Sandeep sir helps to improve visualization of code using proper diagrams and images. Also, proper sequencing of sample examples helps to revise the topic in the future. It’s good that sir gives more time on basic topics in the beginning so that the foundation is strong.

Sir, it’s been a great session with you. The way you taught is very good. It's my first time learning java language and I never felt left out at any point, thanks for taking up every basic topic.

Sandeep Sir is great in teaching he didn’t just give the answers away – he made you THINK. This was sort of frustrating, but it helped me understand the material much better. In tough Situation sunbeam offer an Online class and materials, which allow me to attend the online course by the best instructor. Thank you Sandeep sir, Sunbeam and all his teaching staff

There are two types of teachers, one who teach their students what the syllabus dictates and the other, who go beyond the coursework to teach their students things that life dictates. I really had a fantastic time taking your course. Start from the "Compiling Program without IDE to Reflection" I don’t owe my professional success to my destiny, courage, luck, belief, confidence, or fortune. I owe it to a wonderful scholar like you. Nothing can come close to the inspirational presence of an instructor like you in a student’s journey. You are a great trainer organized, responsive, patient, and able to clearly explain complex topics and nuances. Being so encouraging and doing everything you can to keep us motivated and supported throughout our program. Your knowledge and leadership provide us with a priceless model for our own careers. I am so happy you are part of my education. Thank you for teaching me that emotion and logic exist best together. I learned to truly care about diversity and inclusion through your classes, and I hopefully now spread that message in a passionate but thoughtful way. You’re awesome!

Excellent sessions by Sandeep Sir enjoyed learning core of the Java. Sandeep sir's way of teaching is excellent and easily understood by anyone. Considering the fact that Java is not that simple when it moves to its complex features to any beginner or who doesn't work on Java, it needs much more revisions and continued coding practice. Sandeep sir has made it very easy to understand and taught us exactly how to think in Java. And it clearly seen in the sessions how much hard work has to be done offline to create any notes and diagrams to make things simple and easily understandable. Thank you sir for conducting the sessions. Really looking forward to see you in next advance sessions.

For a long time, I was searching for a good java class where I can learn and understand maximum concepts in a class itself. And Sandeep sir's class was the place where I got every bit of knowledge about core java. He has excellent and deep knowledge of java. He taught every topic and concept in depth. His teaching style which includes explaining a concept by giving real-time examples, drawing beautiful diagrams, and covering every test case of the respective code was noteworthy. I would really like to appreciate sir's punctuality which in turn inculcated a good discipline in me. From now onwards I would like to join every class which is taught by Sandeep sir. Thank you sir for your insight and valuable time! You’re awesome! 

As I was an E&TC passout I didn't have that much of knowledge about the programming but due to modular course of CPP and JAVA from SUNBEAM, I could build a strong foundation for CDAC through which I can prosper now. The excellent teaching methodology by Sandeep sir ensures that no student is left with unclear concepts.
Each and every concepts are taught from very basics. Right now I'm placed in AMDOCS through CDAC campus. Joining modular courses was one of the best decision !

I Got all detailed core concepts of java there is no doubts left . Sandeep sir's teaching techniques and dedication is undoubtedly great. They also told lots of good things about how to increase efficiency to proceed as a great developer always keep focus on building base that further process would be smooth

Teaching faculty is excellent. I like the idea of lab session where our all doubt gets clear and also help us to solve assignments. The way of online teaching is really very good. Thank you Sandeep Sir and team Sunbeam.

All the Topics were covered in details . Sandeep sir took extra effort to cover the extra topics so that students understand Basics . The availability of the PPT and videos also helped the students to revise the topics after the class . I would recommend the class to my friends and colleagues and especially fresher's , since extra effort was put to cover the basics .

It was very nicely designed course which will help us to explore the new opportunities in corporate sector . the module helped a lot to understand the core concepts of Java their applications and functionalities. the learning experience throughout course is very good and so much informative. all the faculty members were so supportive. all the doubts of the students during the session as well as after the session have been addressed appropriately.

The course was very smooth. Ofcourse Sandeep Sir made that happen! One thing I loved about Sir is how he takes you from a beginner level to an expert one. Especially when you are from a non-CS/IT background like I was, its a great help to actually visualize the roadmap of JAVA. He teaches you in a very easy & understandable way & from authentic sources and documentations(which hardly anyone teaches) which makes you believe in his indepth knowledge of JAVA!
