Download the mixed-topic notebooks for our weekly two-hour coding sessions. Each notebook contains six competition-style questions with blank answer cells. Middle- and high-school students work from the same packet, and all six problems are required. Sessions 1–8 build loop and decision foundations; Sessions 9–12 continue with the more challenging mixed practice.
Write a complete Python program for each question: read the competition-style input and print the required output exactly. Spaces, capitalization, punctuation, and newlines matter. Use the Competition Simulation tab to write, run, and submit solutions for automatic scoring. These are original, independent GaSTC-style practice materials created by Bridge Academy; they are not official GaSTC questions.
Loop and decision foundations at the level of Sessions 1–4. Work through these in order.
Gentle mixed practice with input/output, integer arithmetic, decisions, totals, string iteration, and a simple rule loop.
