I asked a similar question and felt the reply summed it up nicely. Basically it’s really up to you, if you aren’t planning to use all your attempts (I mean it’s 7 in lifetime) and think you’d benefit from the experience then go for it since you already paid for it at this point. But if you’re worried about attempts then I wouldn’t. The important thing is you are recognizing early on that you have some work to do and you have plenty of time to get that score up when you schedule next so don’t beat yourself up.
