bash - Linux Shell Script | Wait until installation is finished

Question

I have next week a Linux exam and for that I want to prepare some Shell-Scripts to complete the installations and configurations more faster.

Little example:

sudo apt update 
wait
sudo apt upgrade 
wait
sudo apt -y install net-tools 
wait
sudo apt -y install tree

Everytime I execute this Shell it doesn't complete all the commands. I think it skips all the other commands during the process update.

How can I solve this problem?
