What should I study: electrical engineering or business informatics?

I'd love to study electrical engineering. It's super future-proof, you earn a lot, and you're right in the thick of things. However, it's very difficult, and I don't know if I could handle it. I'm currently at my math A-levels, with 11 points. If I studied harder, I could get 13-14. I've heard 15 points…

direct quoting?

Hello, If I quote a word directly, meaning I put it in quotation marks, but the sentences that follow also come from the same source but are quoted indirectly, is it sufficient to provide a source reference at the end? Otherwise, you'd be doing the same thing twice.
