Can I claim my assignment solutions as mini projects in my resume?
Unless your resume format is prescribed by some external entity, then you can put pretty much anything you want on it. But, don't oversell these as they were all, I assume, a year or less in duration.
And again, unless you are required to use a specific format for some reason, there is no reason for a &quot;Project&quot; item.
Just be clear and honest in any CV.
But perhaps you mean that your institute requires you to produce such a thing for graduation and they set the format. In that case, seek guidance locally about what is accepted and what is not.
