Hello Abeer,

If you have two thumbs on one hand, it could make it difficult to pass the medical exam for NDA (National Defence Academy). The medical standards for NDA are very strict, especially about physical fitness and ability.

NDA requires candidates to have no physical conditions that might affect their performance. If having two thumbs affects how your hand works, like your grip or movement, it might be a problem.

However, every case is looked at individually. If your hand works well and the condition can be treated, you might still have a chance. It's best to talk to a doctor or someone involved in defense recruitment to get clear advice for your situation.

WE WISH YOU ALL THE BEST!
