Does it make sense to invest savings for 5 years in ETFs?

I will probably start preparing for the law exam in 5 years. Such a private revision course costs around €5,000. Does it make sense to invest this money in the MSCI World, for example, instead of having it sitting in the account interest-free or is the time period too short? Edit: I have saved a lot more than the 5k. This is really just about the money that is intended for the rep. I have emergency funds etc. separately. submitted by /u/Tobanga [link] [comments]
