Best Thinkpad for basic online school?

Hey :)

I would like to participate in online classes from January next year.

I'm probably not going to do any tasks that are stressful for a computer. It will certainly be left with participation in online meetings and work with texts and text programs.

I want a reliable wifi connection.

I have a maximum budget of 250€. I have no problem looking at the second-hand market.

But I would like a Thinkpad, which can still cope with current software in the next few years.

What do you recommend for a model?
