Which tablet for training?

In my training, the books are only made available to us as PDF files. So I need a tablet (laptop would also work but I would prefer a tablet because it is smaller and I find it easier to use)

But I hardly know my way around. As I said, I need it to read on it or to open the school books and write notes. A connectable keyboard would probably make sense in the long run, I just don't want to do without the touch screen.
Otherwise I would like to use it privately to watch Netflix / YouTube. And the tablet should be able to withstand a day of school operation without additional electricity, so if I take it with me at 100% I want to be able to cope with it. And it should last for a long time, i.e. At least 3 years

A storage space of 32 Gb would probably not be enough for me in the long run, 64 would be good.
I do not need an extra contract because I will only use it in Wi-Fi networks.

In terms of price, I don't want to spend more than ~ 300 euro, preferably less.

I think all trays are generally very pleasant… I wouldn't worry that much - check out what's cheap on amazon

Usually you score a keyboard for all tablets

The cheaper ones often offer a similar performance to the more expensive ones - it's enough if you get a 200-300 samsung / huawei / windows /… Tablet - it doesn't have to be the 800 euro appel device - the differences are minimal and don't justify the price difference

For example, there's the iPad Pro 10.5 inches. This is available for around 300 euro and is compatible with the apple pencil.

Ipad Mini 5th generation is also priced in the same league and compatible with the apple pencil
the same applies to the 8th generation or 6th gen iPad

(Used, but in very good condition) I would generally recommend buying something used… It saves a lot of money

The S6 Lite is quite good, but no one can guarantee that it will last 3 years, Samsung gives a 24-month manufacturer's guarantee

That is also very good and much more suitable for Netflix. I have it myself in the LTE version, the battery lasts almost 8 hours, in the Wi-Fi version around 11 hours

The Samsung Galaxy Tab S6 Lite, Tab S7 or S7+ would be recommended, depending on what your requirements are for the device.
