Continuity mistake: Ivy extends the threefold invitation to the Botanical Garden event, but a shot later, it's folded and held against her chest. (00:38:00)
Audio problem: Ivy tells Robin that Freeze wants to turn Gotham into "an ice cube" but she's not mouthing those words. (01:38:14)
Continuity mistake: During the press conference, Julie's hand swaps from being lowered to brushing her hair between shots. (00:35:57)
Audio problem: When the telescope is falling and the two people are with Batman, he tells them to grab onto his belt. The audio is terribly clipped.
Continuity mistake: While Bane is driving the limo, after Ivy puts on the wig, the gloves on her hands disappear.
Revealing mistake: At the gala, you can notice the stunt double driving the ice truck for Arnie.
Revealing mistake: In the museum, when Robin breaks the door with his bike you can notice that the door is made of foam rubber or similar.
Revealing mistake: When Batman is about to defrost Robin, he is holding a dummy.
Revealing mistake: While Ivy is fighting Batgirl you can see the stunt double replacing Uma Thurman.
Continuity mistake: Bane is pulling Robin and Batgirl but in the next shot he's pushing them.
Revealing mistake: When Batman is doing his little sliding stunt on the dinosaur exhibit when he and Freeze meet at the beginning, it's obvious that he has roller skates on and is on a rail. (00:05:10)
Deliberate mistake: At the beginning when Batman and Robin are facing Freeze, Robin arrives and crashes through the wall with his motorcycle and leaves a shape in the wall that a motorcycle could possibly make. But, the next shot after Batman looks where Robin is still flying and about to land on his motorcycle, there is a huge bat shape in the broken wall. Obviously done for campy effect, but still a mistake regardless.
Other mistake: During the end credits when the listing for the vehicles go by, it shows "BATMOBILE, FREEZEMOBILE REDBIRD, BATHAMMER, BATSKIFF, and BATCYCLE BY TFX." There should be a comma between Freezemobile and Redbird. (02:02:05)
Answer: There's no way of knowing whether or not she "had the time" to study martial arts. Regardless of her studies, she could have made time to pursue this as an extra-curricular activity. Universities can have classes, clubs, competitions, and student groups for martial arts on campus that anyone can participate in. She may also have been studying it since childhood. She was also a botanist, so even with a rigorous academic schedule, she would likely have more free time than a medical student.
