There's a whole range of different assignments in uni & this'll often relate to what course you're doing.
My biggest ones this semester are:
- short answer exam (chem)
- multi choice exam on laptops (enviro bio)
- short answer/ extended response exam (maths)
- presentation on a project I've been working on (impact through science)
I also know people who:
- don't have exams for their units
- are writing an essay in the exam and basically already know the prompt
- have a take-home exam
Your assessment really depends on the units you choose, and you can check if there is an exam and how much it contributes to your grade before selecting a unit.
It's also very possible that you'd be good at exams if you're in a different environment that didn't stress you out so much
