August LSAT cancel? Help needed please!

Hi everyone! I need some advice on what to do so please bare with me if this is all over the place.

So basically, I took the August LSAT and came out with a 151. Honestly I'm not sure what happened but I was devastated. I took a PT this past saturday after not studying since the exam and scored a 159/BR 170; which is similar to what I was testing before.

I was hoping to get around 165 and apply this cycle. I am registered for the September exam and October. I've been working full time, but starting to take some more time off now to study and hopefully raise my score.

So my questions are:

1. Do I cancel my august score?

2. Do I even bother taking the September exam? Or should I cancel August, take Sept. and also take October?

3. Or keep August, take September, and October? i feel like that would look bad?

4. How can i bridge the gap between my score and BR?? That gap is driving me crazy. Sometimes I think I rush through the prompts/ACs but I ran out of time on two of the LR sections in August so I'm not sure if that's the case or if i was just super nervous.

Sorry and thank you in advance!
