No, focus on your personal statement. This is a great place for you to show your writing skills and your abilities to formulate a good argument for you to be admitted. Dont beat yourself up over an unweighted section, the LSAT is hard enough and the entire application process is hard enough. There are so many ways that you're already proving yourself, just rock an incredible statement.
Hey guys, I'm waitlisted in my top school and I wanted to know how many others may be in the same situation. What's your coping strategy? Are you studying to improve your score for the following year (if you don't get in)? Are you getting your financials in place (just in case you do)? Are you call bombing admissions to see what movement (if any) is happening and/or your index score? Or, are you normal and doing yoga.
Hey! I've been in constant contact with my top 3 schools, I recently asked this sort of question when weighing which sitting to register for. If your top schools are competitive, and you are applying in a competitive stream (ex. general), then you should really aim to take a test before January. A lot of schools do rolling style admissions, so even though you might score high and your GPA is competitive - you might still get waitlisted or bumped for someone who had their application reviewed earlier. I would aim then to hit a home run in your October score, and use January as a last resort if you are looking for 2021 admission.
You're right in that it is online, go ahead and register as normal. Afterward, if you log in to your LSAC, you will notice a statement stating it is the Flex and that you will need to confirm the change, or choose a credit for a later testing date.
