glucose test hack

So I went in for my 24 week check last week and I was speaking to my doc about the glucose test being this is my third baby I knew the deal. She advised me that she can eliminate,  yes I said it ELIMINATE!, the drink. I said ok how she said and I will quote "just eat exactly 28 jelly belly jelly beans it has the same sugar content as the drink" third pregnancy and I'm just finding this out!!!
