Dude, chill. It's only been a few hours since you originally posted, people might not find your post straight away and there's probably a lot of threads like this around right now.
You'll find that you will get into the flow of what to write down and what to leave out pretty quickly - I didn't take the same subjects as you (or anything similar, tbh), but I'd say just write down any info that the teacher is talking about/make notes of stuff as you are working in the lesson, and then rewrite your notes later on (that evening/end of that week perhaps). When you rewrite them, take out any waffle/unnecessary parts and make sure it is neat and easy to revise from later (it's much easier to revise from 'clean'/reviewed notes than messy ones straight from lessons! Perhaps use one of the note methods like the Cornell method, or look up others online...). Try to not write what they say word for word, as this just takes ages and you might not get it all down in time. Use shorthand if you need to, otherwise just make sure you have all the key points/important info down. Lots of colour, imagery, and things like spider diagrams can be useful too!
I'll give you some specific examples of how my lessons usually were, but my subjects were very different to yours and were in very small classes, so I don't know if any of your lessons would have similar formats...
e.g1 - In one of my subjects, in 'theory-based' lessons the teacher would have a powerpoint up and would talk us through the concepts; we would also watch videos and have discussions throughout the session and ask the teacher questions as we went through the slides (it was a very small class, so I don't know if this would be as easy in larger classes). I'd jot down notes on all relevant parts and usually print off the powerpoint slides later. The notes were pretty comprehensive because of the slower pace, so I found I didn't need to make new 'neat' ones straight away.
e.g2 - In a different subject most of our class-based theory stuff was done with whiteboard + pen, with us calling out answers/suggestions & the teacher making spider diagrams or drawings of it throughout; the diagrams weren't as comprehensive but we also got booklets and had practical lessons to actually use the methods in real life (to make it easier to remember). In these sorts of lessons, some of us took notes (either pen+paper, or on computer), and we all took pictures of the board to revise/make new notes from later.
