Hello beautiful people!

I was 6 months to graduating from a BSN program when I failed a second class by less than 1% and was dismissed. However, they give opportunity for re-enrollment after one year. Six months later, I contacted the admission director and was told by the dean to tell them what I have done to improve my ability to succeed if given another chance to enroll. I just need help with what other details I need to include in the content of the letter. I got distracted with personal matters and had trouble answering some test questions. However I've been studying the NCLEX questions for sometime now. Don't know what else to include in the letter. I need help please, NOT discouragement. And no I CANNOT give up; nursing is my passion and I have invested so much time and money in this career path, can't afford to give up or start all over again. I just need to pick myself up, dust myself off and get back on track, but this time with a stronger approach. Thanks in advance for your help and advice with my nursing school readmission letter.
