Prince Georgehas a big week on the books at theLambrook School.

The 10-year-old prince is buckling down for an important round of classroom exams, andPrince Williamevenreferenced the testswhen explaining whyKate Middletonwasn’t with him in Singapore for theEarthshot Prize.

“Catherine is very sorry she can’t be here. She is helping George through his first set of major exams,” the Prince of Wales, 41, said in a speech at the United for Wildlife summit on Monday morning, which fell ahead of the Earthshot Prize awards ceremony on Tuesday.

PEOPLElearned in Septemberthat Princess Kate, 41, would not join her husband at the third annual ceremony for the environmental prize because the inaugural Earthshot Week coincided with Prince George’s exams. Instead, the royal mom is home in Windsor to support him.

However, he won’t be finished with rigorous tests quite yet!

“If the candidate is successful, they will usually be offered a place, conditional on them passing the Year 8 Common Entrance Exam. It is important to note that the Pre-Test is a precursor to Common Entrance or Scholarship exams, which they will still be required to take,” the tutoring firm states.

While the Prince and Princess of Wales’ three kids — Prince George,Princess Charlotte, 8, andPrince Louis, 5 — all attend the Lambrook School near their home in Windsor, the prep school only goes up to Year 8, the American equivalent of 7th grade. From there, George will have to start a new school — and speculation is swirling that he might follow in his mom or dad’s footsteps at Marlborough or Eton.

In October, Richard Eden ofThe Daily Mailreported that Princess Kate, 41, visited the boarding school in Marlborough.

“Catherine was here the other day. It’s been the talk of the school,” a source told the royal reporter.

Princess Kate and her siblings, Pippa and James Middleton, are all Marlborough grads, as is Prince William’s cousinPrincess Eugenie.

Over the summer, Prince George was also spotted with his parents on avisit to Eton College, where Prince William andPrince Harrywent as teenagers.

Although Eton College students are between the ages of 13 and 18, they must be registered before June 30 of the school year the boy turns 10. (Prince George marked his 10th birthday in July.) According to the school’swebsite, “After this, the only route of entry will be through scholarships or Sixth Form entry, which open in Year 8 (for Year 9 entry) and Year 11 (for Sixth Form entry).”

Although Eton is located near the family’s Adelaide Cottage home in Windsor, it is an all-boys school. Because Marlborough is co-ed, Princess Charlotte and Prince Louis could potentially join George there one day.

Both Eton and Marlborough currently cost about $20,000 per term, and there are three terms per year.
