RRB Group D General Science Preparation Strategy (RRB গ্রুপ D জেনারেল সায়েন্স প্রস্তুতির কৌশল)
✅ Preparation Strategy (প্রস্তুতির কৌশল):
-
Understand the Syllabus Clearly (সিলেবাস স্পষ্টভাবে বোঝো):
পদার্থবিজ্ঞান (মূল সূত্র ও দৈনন্দিন জীবনের প্রয়োগ), রসায়ন (প্রতিদিনের রসায়ন ও সহজ প্রতিক্রিয়া), এবং জীববিজ্ঞান (মানবদেহ, উদ্ভিদ, রোগ ইত্যাদি)-এর উপর ফোকাস করো। -
Revise NCERT Books (Class 6–10) (NCERT বই পুনরায় পড়ো – ষষ্ঠ থেকে দশম শ্রেণি):
বেশিরভাগ প্রশ্ন NCERT বিজ্ঞান বই থেকে নেওয়া হয়। মানবদেহের সিস্টেম, গতি ও বলের সূত্র, অম্ল-ক্ষার, বিদ্যুৎ, এবং পরিবেশের মতো গুরুত্বপূর্ণ বিষয়গুলির দ্রুত পুনরাবৃত্তি করো। -
Make Short Notes (সংক্ষিপ্ত নোট তৈরি করো):
সূত্র, বৈজ্ঞানিক ঘটনা, আবিষ্কারক, উদ্ভিদ ও প্রাণীর শ্রেণিবিন্যাসের জন্য সংক্ষিপ্ত নোট প্রস্তুত করো এবং নিয়মিত সেগুলি রিভিশন করো। -
Practice MCQs Daily (প্রতিদিন MCQ অনুশীলন করো):
পূর্ববর্তী বছরের প্রশ্ন এবং গুরুত্বপূর্ণ MCQ সমাধান করে গতি ও নির্ভুলতা বৃদ্ধি করো। দৈনিক অনুশীলন তথ্য মনে রাখতে সাহায্য করে। -
Focus on Important Topics (গুরুত্বপূর্ণ বিষয়গুলিতে ফোকাস করো):
মানব শারীরবিদ্যা, ধাতু ও অধাতু, আলো, শব্দ, রোগ, পুষ্টি, এবং বলের মতো বিষয়গুলি পরীক্ষার জন্য অত্যন্ত গুরুত্বপূর্ণ। -
Take Mock Tests and Analyze (মক টেস্ট দাও এবং বিশ্লেষণ করো):
RRB Group D-এর জন্য বিশেষভাবে ডিজাইন করা মক টেস্ট দাও। তোমার দুর্বল দিকগুলি বিশ্লেষণ করে সেগুলির উপর কাজ করো।
