Ca student - so much worried about my age

Hello friends. I am so much worried about my age. I am 24 years old and I am at IPCC level from last 3 attempts. Everytime i think about my past exams i start loosing my confidence. Some of my friends cleared IPCC exams in their Ist & IInd attempt. But i have failed 3 times. I always get depressed when i look back at my past. I am so foolish that i didnt took my CPT and IPCC seriously. I am so much tensed. Is age my a influencing factor. Tell me. Thank you.
