National Exam Key (مفتاح الامتحان الوطني)

Pay attention to adverbs in the prompt. If you see *"Probably"* or *"Maybe"* , use Might/May . If you see *"I'm sure... not"* , always use Can't . Never use "mustn't" for deduction! (انتبه للظروف؛ استخدم Might مع الاحتمال و Can't مع النفي المؤكد، ولا تستخدم mustn't للاستنتاج)
