It's been a long time since I first registered for the course, but I've finally taken all the core principles. As a computer engineering student, I only took the introductory course, paid for the roadmap, and did several web projects with Spring. Since I was working on the project without fully grasping the concepts, I looked it up, googled, copied and pasted, and experienced many trials and errors and troubleshooting, but now I'm finally getting a feel for what technology I should use. Through the remaining curriculum lectures, I'll internalize some of the theoretical parts and practical skills, and in the next project I'll do, I'll write more restful and better code. Thank you.
