Hii Hukmaram,

You’ve already done 1 year of ITI in Mechanical, which is a good start. Now if you want to do a diploma in Mechanical Engineering online, that’s a smart move.

Some good places where you can do this online are IGNOU (a government university), or some private websites like Coursera or Skill-Lync. IGNOU gives you a proper government-recognized diploma. It's affordable and many students do it while working too.

Along with your diploma, you should also learn some useful software like AutoCAD or SolidWorks. These are important in the mechanical field and will make you better than others.

side by side learn these skills from YouTube or low-cost courses. After that, apply for small jobs or internships to get experience.

Just stay focused and keep learning.
