if you want to study law in the future what subjects in IB do you have to pick?

Hey, it is not "low and high", it is Higher Level (HL) and Standard Level (SL). Anyways, in most cases, English is the only requirement for law. So I recommend English at HL. As for another subject, there isn't anything else that is directly related...although for Group 2, you could choose a second language that is useful in your country. As for Group 3, take history. I suggest you to take these two at HL. Group 4 (natural science), Group 5 (mathematics) and Group 6 (arts or elective) are not that relevant for law, so these could be taken at SL.

Lol if you are planning to be a lawyer, I suggest you to start typing better English.

Well, as a fellow IB student, the more HL classes you take the better. HL is accepted more as college classes and credits. Some colleges take them as individual credits, and some have the diploma count as freshman year in college, so it all depends on what colleges you are interested in.

You can pick political science,history and economics.

Hey I want to do a law course and I'm doing the IB.

Unis don't really specify subjects. But its recommended to take HL Enlgish and History. Another HL of your choice is fine (usually Psychology or Economics). But If you're planning on studying in a different country while at uni take the language of that country at HL. HL Math also looks good if you do well.

But talk to your councillor! It will help
