Probably. The maximum American Opportunity Credit (AOC) is $2500. If you're not getting something close to that, it's better to wait. But, keep in mind, that in addition to the 4 time rule there is a completion of 4 years of education rule. If she graduates before using all 4 times, the others are loss (the AOC can be claimed in the year of graduation).
High school students are not usually eligible for the American Opportunity Credit, unless they are officially enrolled as a degree candidate. From pub 970: "Example 3. During the 2015 fall semester, Larry was a high school student who took classes on a half-time basis at College X. Larry wasn't enrolled as part of a degree program at College X because College X only admits students to a degree program if they have a high school diploma or equivalent. Because Larry wasn't enrolled in a degree program at College X during 2015, Larry wasn't an eligible student for tax year 2015." Reference: https://www.irs.gov/publications/p970/ch02.html
The ability of the parent of a high school student to claim the credit or deduction is limited. If these courses are provided by an eligible college, this cost qualifies for the Lifetime Learning Credit (LLC). The school must have policy of granting college credit for that course, already taken, if the student ever enrolls there. In other words, it is a requirement that the course be a college credit course, even if the student isn't currently a college student. It’s not that the student is post secondary, it’s that the course is post secondary. Books are not a qualifying expense, unless included in the course fee.
