Hi! So I've tried the Forage and if you read their terms, you can actually include that into your work experience granted you actually did the work properly and treat it as though you were an intern. I did experience for law as well but I didn't do it seriously - I treated it as a learning course? If you wish to apply it to your personal statement (and you've done it properly), you could talk about how you got a glimpse of your intended area of study as a career, then connect the dots? However, I don't necessarily recommend it to be an important part of your ps - if mentioned, keep it relevant, short and manipulate it to convince.
Here's an example of a first draft I had for my own personal statement (skipped a few lines and not to be taken as a guide):
"Through my virtual work experience with *insert company*, I was given insight as to how lawyers thought and tackled challenging morality and ethics, as I found it impacted how each case would be approached and handled. A false case I worked on (because they give you made up situations close to reality) involved domestic abuse inflicted on the wife of the abuser. I initially thought the solution was simple: the husband was guilty and should serve time, however, we found out the wife had also attacked her husband........ My final verdict sought for the husband to be jailed and the wife in rehabilitation. Concerned that my current knowledge is shallow to justify my thoughts, I am keen to explore more theoretical situations and the intricacies of the criminal justice system at university."
Keep in mind that unis don't expect you to have work exp, as they know the situation we are in with Covid. Besides work exp, you could take law courses, they're really good to help with interviews - there are really good free ones on FutureLearn (where u can get a certificate for it, with a price ofc), and EdX.org (search learn law with online courses and lessons). The point is to be able to connect the dots and make everything relevant through critical reflection. Hope this helped!
