I just finished my first LSAT Practice Test and I'm a bit confused on what to expect when I actually take the test.

So I read on this reddit post that the actual LSAT is 6 sections 4 graded, 1 non graded experimental, and writing section.

But when I took the LSAT Practice Test it only gave us four sections.

Then I find out now with COVID it's only three sections of the test, but then it's going back to the original?

What exactly is the correct answer, my brain is complete mush right now and I just want an understanding of what to expect in the future.
