Downloading Bitcoin core


Hi, fellow students, Ivan
I am looking forward to this course . I did the Blockchain deep fundamentals which was very helpful.
Now I am getting my hands dirty.
I started to download Bitcoin Core even though I had 180 GB space.
Firstly, my internet becomes too slow, actually unusable, so I may need to stop it.
Then I saw this on the Bitcoin Core site:

Bitcoin Core requires a one-time download of about 210GB of data plus a further 5-10GB per month. By default, you will need to store all of that data, but if you enable pruning, you can store as little as 6GB total without sacrificing any security. For more information about setting up Bitcoin Core, please read the full node guide.

For testnet and regnet mode, do I need to complete the download of the entire Bitcoin history?
