Hello student,

You can write the content on a paper or whatever medium is comfortable to you and makes you work more better and creatively. However, if you want your content to be transferred or sent to somebody, sending it on a written paper nowadays is out of date. So, you can type it down or use speech to text convertor to transport your written work into a digital copy that can be easily accessible without any hassle. As a freelancer, you may also have foreign clients who may have a better experience of a digital imprint rather than a Handwritten copy

I hope this helps, All the Best!
