Hi Akshada, thank you for taking the time to read and support my article! I think the most important things that you can focus on in parallel with the course is developing a strong understanding of industry knowledge (learning how you can apply your data analysis skills to solve a given problem in a particular industry of your choice), and making sure you understand the fundamentals of working with spreadsheets. A lot of data analysis can be done by just using an Excel or Google spreadsheet. If you want to get more in depth, I would say the next step would be to really delve into the fundamentals of programming and basic statistics.
