Sequences: Confusing nth term with partial sum. — Label a_n and S_n separately and use a_n = S_n - S_{n-1} when needed.
Vectors: Treating position vectors and direction vectors as interchangeable. — Mark points as position vectors from origin and sides as d…
Logarithms: Accepting roots that make log arguments non-positive. — Write domain restrictions on the first line and test final roots.
