TLDR; Select any two LSAT PrepTests from LSAC.org. Read over one at your leisure. Don’t worry about any convoluted language (a significant part of the test). Take the second test strictly timed. Make sure to answer at least 20 questions in each section.

Taking a warm diagnostic is crazy-important primarily because it informs students about how much time and energy they can expect to put into their studies. Nothing inherently wrong with taking a cold diagnostic, but doing so provides less information for moving forward.

When perusing the warm-up test, don’t worry about the convoluted language. Believe it or not, it’s learnable.
In addition, it might seem that multiple answers are right or none of the answers are right. Please know every question features four definitively wrong answers.
When taking the strictly-timed test, hit it as hard as you can. Get warmed up a little bit by reading over that previous test. Definitely try to answer at least 20 questions in each section, all of them if possible.
The large majority of questions feature three answers that are fairly easy to eliminate (especially once proper LSAT strategies are applied). This means that many students can answer a question fairly quickly and have a 50% chance of getting it right.
At the same time, no penalty for wrong answers. This is why students want to try to answer at least 20 questions, if not all questions, in each section (have anywhere between 25 and 27 questions).
Under no circumstances should you give up in a particular section. If a question seems too difficult, make a good guess and move on.
Don’t be concerned if your score is lower than you might have hoped. The LSAT is often referred to as a skills-based test, which can be a strange thing for many students. But with the right kind of work, the LSAT is most definitely learnable.
