مرحبا

انا تخصصي احياء دقيقه - كليه علوم
اختبرت بكل الاقسام والاختبار كان جدا رائع مافيه اي شي من اللي ينقال ذاكري تمام وتوكلي على الله
بس خلي بالك خريجي كليه العلوم نفس الاختبار سواء كان احياء دقيقه او كيمياء حيوي والتركيز بالاختبار ع الاحياء الدقيقه
ومثل ماقلتي التصنيف حايكون فنيه واذا توظفتي يتغير بعد سنتين لاخصائيه هذا الكلام تاكدي منه انا قبل شهرين مختبره يعني قفلي اذنك عن الكلام الفاضي لانه انا سمعت كثير كلام احبطني

اتمنى اكون افدتك بشي والله يوفقك عزيزتي

هلا اختي انا تخصصي كيمياء حيوي وامتحنت الاسبوع الي فات والحمد الله نجحت بنسبة عاليه ولاتخافي ترا الامتحان يجي في كل لاقسام وهو نفس امتحان الفني
انت ذاكري من الملخصات اللي في المنتدى وركزي على نماذج الامتحانات وتضمني النجاح ان شاء الله ^_^

أنــآ اختبرت كل اسبوعين والاسئلة بس كانت بالمايكروا

ولم اوفق في الاختبار
اللي اختبر وتخصصه أحيـاء دقيقة يقولـــــــــــي///لاني شوفت لي دكتورة تذاكرلي المنهج
يمكن يكونوا غيروا الاسئلة

الحزن العتيق .. سكر زياده

الله يسعدكم والله ريحتووووووني باجاباتكم

اختباري باذن الله في شعبان ان شاء الله اتوفق وانجح

الله يسعدكم يارب ويفرحكم بالوظيفه





ورده تحت المطر

ان شاء الله المره الجايه تتوفقي بالامتحان

انتي طيب بأيت مدينة ؟؟

بنات بسألكم هل النتيجه تطلع لك على طول بنفس الوقت

ومتى تقدري تستلمي بطاقه التصنيف

وكمان بسالكم لمن قدمتوو طلبوا منكم دورة الانعاش القلبي الرئوي ؟؟

وايش طلبوا منكم اوراق ؟؟

انا من المدينه
والنتيجه تطلع ع طول/وبطاقه التصنيف تاخذينها بعد اسبوعين زي ماسمعت
ولازم يطلبوها منك دورة الانعاش الرئوي
الاوراق اللي طلبوها :
صورة من وثيقة التخرج وصورة من دورة الانعاش ودفع رسوم عن طريق بنك الاهلي انتي لارحتي لهم يعطوكي رقم حساب البنك
صورة من شهادة التدريب والتقيييم وصورة من كرت العايله او صورة من البطاقة الشخصية
رسوم الهيئة 840 ورسوم الاختبار 350 ترى كل وحده
لها حساب مختلف

ماشاء الله اخت وردة تحت المطر ماقصرت جاوبتك على اسئلتك
انا لسه ماستلمت البطاقه وقالولي راجعي بعد اسبوعين وموعدي معاهم الاربعاء الجاي ^_^


وردة تحت المطر لاتزعلي نفسك وانشاء الله بتنجحي في المرة الجايه
حاولي تركزي على النماذج وترا الامتحان سهل مايبغاله انك تروحي لدكتورة وكذا
كل الي تحتاجيه تعرفي ايش تذاكري وكيف وزي ماقلتلك النماااااذج مرة راح تسهل عليكي
وموفقه ان شاء الله

العفو اختي سكر ماسويت الا الواجب
ماعندي نماذج اسئلة فني احياء دقيقة والاسئلة اللي بالمنتدى تختلف عن الاسئلة فني أحياء دقيقة
القرار هذا جديد ماله غير شهرين
ودراستي كانت بالعربي مضطرة اشوف لي دكتورة تشرحلي

شكرا على اجوبتك

طيب البنات قالوو ان الاسئله راح تكون في كل الاقسام

مو بس احياء ؟؟

العفو خيتو
البنات.اللي قالوا لك كذا وش تخصصاتهم ومتى اختبروا ؟
اللي قريته من المنتدى واللي توهم اختبروا قالوا ان اسئلة فني الكيمياء الحيوية هي نفسها اسئلة فني مختبر

ارجعي اقرأي اردود الاولى


اتوقع كاتبه مختبره من شهر ووحده اختبرت الاسبوع الي فات


احسن اتصلي على الهيئه بنفسك واتاكدي


الله يوفقنا

برجع أتصل عليــــــــــــــــهم..
اللي اختبروا وجاتهم الاسئلة نفس اسئلة فني مختبر ونفس تخصصي اختبروا قبل شهرين ( قبل ما يجي القرار الجديد)
