Continuity mistake: When Robin steps foot into Poison Ivy's lair she is laid out on her flower bed. If you look at the sleeves of her costume, the ends of the sleeves are fringed in a simple leaf like design. Robin spurns Poison Ivy's affections, and an enfuriated Ivy pushes him into the lily pad pool. She is then confronted by Batman, and a soon to arrive Batgirl. Now - look at the huge, obvious, black rubber "thorn" bracelets that suddenly appear on each of her wrists. (01:37:25)
Continuity mistake: At the observatory, when Bruce gives Dr. Isley's (Poison Ivy) proposal back. She grabs it with the printed part toward her, but in the next shot, she's holding the paper with the painted part facing away from her. (00:37:10)
Other mistake: While fighting Mr. Freeze (and Bane) at the Gotham Observatory, Batman, Robin & Batgirl all have batsuits on, with silver bat (or robin) symbols on their chest. But while they are giving Alfred the cure to Stage 1 of McGregor's Syndrome, for some reason they have changed clothes before giving him the cure. Because now (other than the fact that they have all taken off their masks) Robin has on his original robin suit (with the red robin symbol across his chest) and Batgirl has on a gray t-shirt. (01:55:25 - 01:56:15)
Other mistake: When Mr. Freeze threatens to freeze all of Gotham City, he has a big snowglobe in his hand. He freezes the snowglobe, then shatters it in is hand. When he crushes it open with his hand, the inside of the snowglobe is empty. There is no water, frozen or unfrozen, that comes out of the snowglobe when it breaks. (01:23:50)
Continuity mistake: When Dr. Freeze bends down to kiss his wife right before his accident, there is a tube of some sort behind her (in the distance), then as he kisses her the tube is gone. (00:20:15)
Continuity mistake: When Dr. Pamela Isley and Bane first arrive in Gotham City and are driving to the Gotham Observatory in their (stolen) red car, Dr. Isley is putting on a wig. When she grabs the wig out of the box and puts it on her head, you can see that she has black gloves on, but the gloves are missing when she is looking in the mirror and says to Bane "Gotham Observatory, Bane. And step on it." (00:34:05)
Revealing mistake: After Batman slides and kicks Freeze, there's a protruding lump under his clothes where the safety cable holding him was.
Continuity mistake: When Poison Ivy first enters the Turkish Bath she is wearing a green top, tights and boots but as she is redecorating just after ejecting the gang members she now has brown tights and high heels. (00:59:10)
Continuity mistake: When Freeze freezes Frosty while he holds a newspaper, Frosty's position and the way the newspaper folds change between shots. The position and number of icicles around him also change drastically.
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)
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.
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.
