Officially named Course 1, Blooms (ブルーム) is the name for the top 50% of people who enter First High School. As opposed to the Weeds, Blooms have higher magic capabilities as sorted by the entrance test. This tests magic technical skills including application ability (speed of magic design), magic tolerance (scale of Magic Sequences), interference strength (strength of rewriting Eidos) and Magic Power which is a combination of the three. The name Blooms comes from the symbol of First High, a flower with eight petals, being present on the clothing of the Course 1 students and not the Course 2 students. There is a general feeling of superiority among the Blooms just by being in Course 1.
The Course 1 students are sorted into classes A, B, C and D. Class distribution is supposed to be evenly split between the four classes, although exceptions occur which give educators considerable headaches.
The curriculum between Course 1 and Course 2 students is exactly the same; however, students in Course 1 have access to private lessons and magic teachers which the Course 2 students do not. The lack of availability of instructors has given the Course 1 students a more in-depth instruction, while the Course 2 students only study off terminals.
Magic education is a trial-and-error thing and accidents, which go beyond the level of minor mishaps, can easily happen directly through magic slip-ups from practice training and experiments. Students sometimes lose the ability to use magic after such accidents. Such vacant places are filled up by Course 2 Students as replacements. Although accidents resulting in deaths or handicapped bodies have been eradicated due to accumulation of know-how, the number of students who drop out being unable to use magic is not small.
