Tablet for students under 600 euro?

I'm in the process of preparing myself for my studies and I think it would really make sense to get a tablet! (I have a laptop, but it is very slow on the one hand and very large on the other)

Since I'm currently doing an FSJ, my financial resources are somewhat limited and I actually don't want to have to spend more than 600 euro on the tablet myself.

(I will look at the accessories separately) My cell phone runs on Android and is already connected to my laptop via Google, so I guess that it would make sense to stay with an Android system. Otherwise I actually have no things that are really blatantly important.

Does anyone have any good suggestions?

Look for a convertible, this is a mixture of tablet and laptop. Acer devices are cheap and good.

A good recommendation would be the iPad (not iPad pro, just iPad). The cheapest version costs 379 and depending on how much GB you take and whether you choose with SIM card or without, it will be more expensive.
The Apple Pen would be a good accessory. You can write very well in class with the right program. For more information you have to check the Apple website.

But if you absolutely want to stay with Android, I can't help you.
