بورڈ پیپر استعمال کرنے کی ہدایات
مبارک ہو! آپ کا بورڈ پیٹرن پیپر تیار ہو چکا ہے۔
اس پیپر کو اپنی ضرورت کے مطابق تبدیل کرنے کے لئے درج ذیل ہدایات دیکھیں:
- کسی بھی سوال کے متن پر کلک کریں، سوال کا جملہ صرف اسی پیپر کے لئے ایڈٹ ہو جائے گا۔
- سوال کے ساتھ موجود ↻ (ری لوڈ) والے آئیکن پر کلک کریں، سوال تبدیل ہو کر سوالات کے بینک سے دوسرا سوال آ جائے گا۔
- اوپر والے کنٹرولز سے MCQs کی ترتیب (ٹیبل / بورڈ اسٹائل کمپیکٹ) تبدیل کر سکتے ہیں اور بائیں سائیڈ بار سے ببل شیٹ کو چھپا یا ظاہر کر سکتے ہیں۔
- جب پیپر فائنل ہو جائے تو دائیں اوپر موجود Print بٹن کے ذریعے پیپر کو پرنٹ کریں یا PDF کی شکل میں محفوظ کریں۔
یہ ہدایات والا باکس صرف پہلی مرتبہ بورڈ پیپر بنانے پر خودکار طور پر دکھایا جاتا ہے۔ بعد میں آپ جب چاہیں اوپر موجود Instructions بٹن سے دوبارہ یہ ہدایات دیکھ سکتے ہیں۔
