Cressida, 24, is said to have her heart set on a career in teaching and is studying so hard she was even photographed taking child development textbooks into a charity concert she attended last week.
“She’s keeping herself busy and working hard,” a friend told the Daily Mail.
Cressida is a trained dancer, but has decided to pursue a more respectable career now she is dating Harry.
Harry and Cressida have been dating for around 18 months after they were introduced by his cousin Princess Eugenie.
They have been inseparable, but have been apart for the past three weeks as Harry takes part in a trek to the South Pole for his beloved Walking with the Wounded charity.
The couple will be reunited in a couple of weeks and are said to be planning a romantic trip to Africa or Switzerland to make up for lost time.
