The 19-year-old formed one sixth of the first ever British rhythmic gymnastics team to compete at an Olympic Games, helping them finish 12th at London 2012.
That came after they successfully appealed their non-selection, and with the squad deciding to go their separate ways Cassar has been enjoying some much-needed rest and recuperation.
After a year out to concentrate on London 2012, Cassar is back studying at King Edward's School in Bath while going back to her roots and training as an individual athlete.
Having represented Gibraltar at the 2010 Commonwealth Games, the 2014 edition in Glasgow are attractive to Cassar, but given the year that's been she won't make a decision any time soon.
"We went through so much in the build up to London 2012, so many ups and downs, that I don't think I will ever be able to forget it," said Cassar.
"I might go for the Commonwealth Games in Glasgow in 2014 but I also want to do other things and go to university and study media and journalism and try and become a TV presenter.
"Whatever happens, I have reached my main aim in life so I am quite happy. I will always be an Olympian and that is something that no one can take away from me.
"I am enjoying being back at school and having a bit of a break. I am still training most days, though, apart from Sunday."
While the majority of the British team have gone their separate ways following the conclusion of London 2012, Cassar still lives with Jade Faulkner in Bath.
And, with a lack of funding for the rhythmic discipline of gymnastics in Britain, Cassar admitted it was not ever likely that they would continue competing together.
"We have split up as a group, some have gone into coaching and the rest of us have gone back to being individuals," she added.
"That was always going to be the case because we don't get the funding, there was no way really that we could have stayed together and trained 24/7."
