How is Julius for University level math and physics?

So I’m planning on studying for a math course I need to retake in August and thought it would be a good idea to take some help from some type of AI to help me out. Did some tests but it did not manage to get all the way on the questions I managed to ask it with my free version, not sure if the swedish also makes it harder for the AI to figure things out. So my question is if it is any different if you pay for it

It shouldn’t have issues with reading Swedish as you can have Julius answer you in Swedish by changing the language settings in the tips box. As for upgrading, you get unlimited messages so you can really tease out that information you need. I think the trial gives you just the basics, whereas the subscription allows you to try out more capable models for different tests.
