I recently finished the first module of the Data Science course. It's a lot of work, but with the help of the many different resources and people available to you throughout the process, it really pays off. The biggest hurdle for some will be learning to ask for help, and Practicum encourages it throughout the process. For me personally what really has helped me solidify my learning is the projects. Every major section so far has had a project that you get feedback on and sent back to you until you get it right. And all of my reviewers so far have added in little extra tips to help along the way or make things simpler for myself above and beyond the normal project review. Added a photo of what I've completed so far so that others can see I'm actually taking the course
