Jolt's made it quite clear in the previous thunderbolts issues that she doesn't like school and doesn't want a normal life. Just what is bothering her about school? The closest that the reasons for Jolt not liking school has been when she was remembering her old school before Onslaught, when she was happy. With Onslaught her whole life changed, she lost friends and got turned into Jolt by Arnim Zola. In Thunderbolts #32 Hawkeye tells Jolt that she will have to talk to Moonstone about school since Hawkeye thinks there is more to her attitude about not wanting to got to school then normal kids hating school which leaves another thing for issue #33 to deal with.
In Thunderbolts #33 we find out Jolts reasons for not wanting to go to school during Onslaught everyone she loved, parents and friends were killed by a stray blast from a sentinel striking the building they were in. Her whole neighbourhood was devastated and she tried to survive until the Rat Pack got to her. Jolts normal life was destroyed so she has been playing superhero to avoid dealing with it and school is just a reminder of what her life was before, not a very pleasant memory.
