“The players are excited about the competition and we are looking forward to the challenge,” she said.
“We have been training hard since the squad assembled early in January and we have paid special attention to the areas of our game which let us down in Dubai.”
During the tournament in Sao Paulo on Saturday, the South Africans would be looking to make up for a disappointing first leg performance in Dubai in December.
Only five tournaments remained in the World Series for the team to play their way into the top four and automatically qualify for the 2016 Rio Olympic Games.
“We have raised the intensity of our training sessions significantly to simulate a match situation at training, while another big focus has been on sticking to our structures under pressure.
“One will never face an easy draw in a competition of this nature, so we know we have to rise to the occasion, regardless of which teams we are up against.”
The South Africans were up against stiff competition in England, Canada and Russia in their pool matches on Saturday.
Canada were currently in third place on the log while England were fifth.
Coach Renfred Dazel made two changes to the team which travelled to Dubai with the captain Jordaan and Siviwe Basweni making their returns.
Sevens squad: Siviwe Basweni, Lorinda Brown, Phumeza Gadu, Rachelle Geldenhuys, Nosiphiwo Goda, Veroeshka Grain, Zenay Jordaan (captain),
Jacqueline Kriel, Marithy Pienaar, Fundiswa Plaatjie, Mathrin Simmers, Shona-Leah Weston.
