Hello friends and students ! मैं D.K. Deepak sir!
NEET और प्लस टू बोर्ड की अच्छी तैयारी के लिए मैंने क्वेश्चन सेट तैयार किया है और यदि आप इन प्रश्नों को अच्छी तरह से समझ कर प्रैक्टिस करते हैं तो मेरा विश्वास है कि आप NEET की तैयारी काफी अच्छे ढंग से कर सकते हैं। ये सारे प्रश्न पूरी तरह से कांसेप्ट पर आधारित है और मैं आप लोगों से यह कहना चाहता हूं की इन प्रश्नों को solve करने से पहले NCERT पुस्तकों का गहन अध्ययन करें क्योंकि इस भ्रम में नहीं रहिएगा कि अधिकांश प्रश्न other books से आते हैं ,मात्र 10 से 15 % प्रश्न ही आउट ऑफ एनसीआरटी होते हैं। Best of luck !
