Datamites offers great online courses to learn SQL, Excel, Tableau, and Python. Their courses are easy to follow and beginner-friendly. You can practice real-world projects while learning. Datamites provides certifications that boost your resume. It’s a good choice for anyone wanting to build data skills quickly.

Yes, your thought process is excellent. Some of the courses on Coursera or Udemy, or any other free platform, don’t have deep knowledge on key topics and are pre-recorded with outdated content. I would suggest to you the IIM SKILLS data analytics course, it’s a 6-month course with structured learning. live instructor-led program, offers one-on-one mentorship from ex-IIT Mumbai alumni, covering in-depth knowledge on Excel, Python & R, SQL, Power BI from 8+ live projects, 10+ case studies and helps in preparation of 10 global accredited certifications along with guaranteed paid internship and assured placement support. 

I joined the Master Data Analytics Course in IIM SKILLS a few months ago with a view to enhancing my analytics tool skills. It was good combination of theory as well as practice, not just lectures but practical practice using Excel, SQL, Python, and visualization tools. It was more like working on mini-projects rather than studying theories.

I have learned R reading stack overflow and watching YouTube. Nowadays there is also AI, do not spend money on more courses, all the entry level information is for free online.

Kaggle has lots of courses for python, they are free.

Much better to start to work on projects though. Possibly something that is full stack, e.g. how to web scrape some data with python, store it in a mysql database, analyse it and then visualise it in an excel report or a dashboard in tableau. In a real job you will need to learn to use many pieces of software, you can’t learn all of them in advance. Learn how to learn while working on a project. No course is going to teach you that and this can be your advantage.

DataCamp in general has been alright for me. But the best process has been watching some YouTube tutorials for familiarity and then just finding datasets to actually play with. I’d recommend just coming up with a project that has a way to mesh all of those together.
