I'm sorry to hear. I found that studying the rationales in the prep guides 4th and 5th edition and using ADPIE and ABCs is what really helped me. I also really took my time, I only had 15 minutes remaining at the end of the exam. I wish you luck on your second attempt! I'd say focus more on the rationales than the questions themselves. You'll have an easier time rationalizing the questions on the exam.
