Example (LESSON_UID = "basic-104")

# Basic drill L104 topic-10 micro-3 pattern-10
LESSON_UID = "basic-104"
spin_a, spin_b, spin_c = 209, 664, 784

def gate(v):
    if v < spin_a + 3:
        return "low", v ** 2
    if v > spin_b + 104:
        return "high", v // max(1, 3 + 1)
    return "mid", v + spin_c

cand = [9, 7, 53]
for candidate in cand:
    lbl, val = gate(candidate)
    print(candidate, lbl, val)
