🔺رغم هذا كله مامقتنعين بعدكم انو هاي الحاله طبيعيه وكل إمتحان تتكرر فعادي كل الطلاب هيج ..

إن شاء الله تجاوبون وباعلى الدرجات 🤲

🔺 بشرو شلونها الأسئلة ؟

اذا احد حصل الها تصوير خلي يدزها بلا زحمة

🔺شباب منو اعتمد على المراجعة المركزة وجاوب وشكد كانت نسبة التشابة ؟

🔺 لا تفكرون حاليا بأي شي بعد توجهو المادة الثانية

🔺 الي كدرتو تقرون هاي هيه وإن شاء الله تنجحون الي مالحك أو يخت 😅
خلي يركز على بقية الأمتحانات وهاي تسهل إن شاء الله

🔺 شباب شفتو الامتحان الشامل بإضطرابات الأيض مفيد ؟

يعني نكرره للفطريات لو المركزة كافية ؟
