Stucked and *ucked

"Hello everyone, I'm seeking advice. I cleared my CA Intermediate Group 1 in my third attempt, but I'm struggling to pass Group 2 despite two attempts. In total, I've made five attempts for both groups, and my inability to clear Group 2 is frustrating me.

I've been studying always but one subject, Costing, has consistently been my downfall. I feel sad and unsure about how to proceed. After so many attempts, I feel like I'm falling behind my friends, who are nearing the completion of their articleship and preparing for their finals.

At 21, I'm feeling disappointed and sad about my situation. Becoming a CA has been my dream since school, but now I'm losing motivation. I feel like I have the potential to succeed, but I'm struggling to utilize it due to distractions and a lack of concentration.

Whenever I sit down to study, my mind wanders, and I feel depressed. I'm torn between leaving the course and persevering. Please, give me advice on what to do next." Should I continue it or leave it as it's a high time
