The Rhodes Scholarship is THE most prestigious scholarship available to undergraduate students in the US. Every year, each university nominates their top 2-3 students to apply. Only 32 are chosen every year. The scholarship pays for 2-3 years study at Oxford.
To put it in perspective, the Rhodes scholarship was what put Bill Clinton, a farm boy from Mena, Arkansas, on the path to US presidency.
I know Tanya personally, and she's my friend's cousin. She has lived and studied in Jordan until she moved to Stanford to study Human Biology. She's very humble and extremely active. I really hope best for her, and I hope more Jordanians will win this scholarship in the future.
The scholarship is available to citizens of about 22 countries. It'll be great if it becomes available to Jordanian citizens also one day. I'm not sure how we can make this happen.
