Any mechanical engineering seniors?? Need advice

Seniors I need a advice I am currently joining mechanical engineering in a NIT, and really interested in aerospace and core fields.. and wanted to just get more familiar with the stream..

Could you please suggest me some new software skills that I should be working on with the core field to enhance my knowledge and capabilities.

It can be anything like robotics, rover, space, core mechanical design... I need courses and suggestions to do..

Thank you.
