Band 10 Mentality + Study Group

Hi everyone. Has any of you thought that you passed Level 1 for sure in June, only to realize later that you missed it by 2 to 3 questions and somehow ended up in Band 10? I like to get an idea of how many people are in the same boat as me and is for sure retaking the exam in December. Also, anyone interested in forming a study group for the December Exam? I am located in NYC. Cheers, Li
