It has very good content, but I don't like the audio, or that the subtitles do not match what it says, I do not speak English natively and it is difficult for me to understand it many times, it also does not follow conventions and although it is not the objective of the course, they are necessary for people who work with this language

By Moudhani D on 11/21/2020

Good

By Mohan N on 11/14/2020

Its good to gather knowledge for rapid Sprinboot development

By SOWMYASHREE N on 11/7/2020

Very good explanation with examples. I was actually not knowing anything on Spring Boot, now I have learnt about it. Really amazing.!!
Thank You so much Reddy Sir!!!

Nice Information

By Mithun Jaisingh on 10/21/2020

The course is simpler and explained in a good manner. For Beginners it would be a good course to start learning Spring boot

By Anonymized User on 10/15/2020

To some extent the instructor comments are about actions (put an annotation, add a plugin configuration, add a bean etc) but not about the concepts behind this nor about how it works. REST style overview (URIs etc) and application monitoring chapters are ok but others are so so. In general the course could not be considered as a best practice for REST APIs development but just as a teoretical overview. It seems all this stuff is based not on a practical experience but rather a theory.

it's long but very informative

By Sabarinathan Perumal on 8/26/2020

Its good learn the Spring Boot Concept as a Beginner who knows the basic java concept. The way they taken care here is nice to understood easily. I think almost they covered Spring Boot topics except Spring Security. If it might included, it was full filled. But Any way i understood easily and i did the assignment as my own knowledge and interested to learned this course.
