In Session will air Jodi Arias' testimony in full Tuesday morning on truTV at 9 a.m. ET.

Jodi Arias, the admitted killer at the center of what could be the most-watched murder trial of 2013, testified Monday. She'll be back on the witness stand at 12:30 p.m. ET Tuesday to continue her testimony.

WATCH: Arias: Alexander attacked me

Will she explain why she killed her ex-boyfriend, Travis Alexander?

Will she convince the jury?

Will she be able to save herself from the death penalty?

Arias has told multiple stories about Alexander's death.

Soon after his body was found in June 2008, Arias told police she was not involved in Alexander's death. Later, she changed her story and told investigators that she witnessed two intruders break in and kill him. She eventually admitted to killing Alexander, claiming self-defense.

6:23 p.m. ET: From In Session's producer in the courtroom:

The jurors appear engaged, sitting forward and watching as Jodi speaks, she turns her body toward them before she answers the questions from her attorney. They do not appear to be taking notes. They occasionally look down but, for the most part, they watch her as she directs her responses to them.

6:18 p.m. ET: Defense attorney Nurmi is asking Arias about how she visited Juarez in Medford, Oregon. Arias says she went up to visit him several times, while he lived in Medford.

6:09 p.m. ET: Arias said one time Juarez came over to her house and they started to argue, and he strangled her. She says she almost passed out.

"Our argument escalated and he approached me and spun me around. And he was very much into martial arts and he had some kind of hold, I guess it was called a strangle hold. So he started strangling me. Just for a few seconds. And then he let go. I almost passed out. I fell on my knees,” said Arias.

6:03 p.m. ET: Arias said Juarez treated her well until she found out that he cheated on her. This made her move out of his house, and she moved in with her grandparents.

“It didn’t make me feel good. He was very loving and poetic with this person and I could tell he had real feelings for her. I guess i felt jealous a little bit," said Arias.

6:00 p.m. ET: Defense attorney Nurmi is asking Arias about the jobs she took to support herself after she moved out of her parents home. Arias says she worked at a restaurant. She gave Juarez money for food and clothes. The power was shut off one time during the winter.

4:43 p.m. ET: Arias said she moved in with her boyfriend at 17, because of one episode of abuse. She eventually dropped out of school to support herself.

4:39 p.m. ET: Arias said her father could bench over 500 pounds when she was a child. She said sometimes her parents would both hit at the same time, and her mom would dig her nails into her. Right now, she is explaining why she did not graduate from high school.

“[My dad] didn’t leave welts as often as my mom, she also used a belt. My dad was very intimidating so I don’t think he needed to hit as quite as hard to get the point across,” said Arias.

“I don’t think she meant to. But, my mom broke my brother’s vein in his wrist because he was putting his hand behind his back to block one of her blows. And, um, you know, once I became a teenager my Dad would get rougher and rougher.”

4:32 p.m. ET: Arias is talking about her years in high school, and how her parents did not support her interest in art.

4:25 p.m. ET: Defense attorney Kirk Nurmi asked Arias why she told "Inside Edition" that no jury would find her guilty. Arias said she planned to kill herself before a trial was ever held.

“So, I was very confident that no jury would convict me because I planned to be dead. Probably the most bitter words I’ll ever eat," said Arias.

Arias also recounted how her family disciplined her as a child. She claimed her mother would hit her with a wooden spoon, and her father would hit her with a belt.

Arias also said she was nervous about testifying.
