But here’s the secret: The exam uses similar logic without the visual game.
If you’re working through Project Lead The Way (PLTW) Computer Science Essentials (CSE) and have hit a wall with Activity 4.3.1: Terminus — Part 2 , you are definitely not alone. activity 4.3 1 terminus part 2 answer key
while get_pos() != goal_pos: player = get_pos() block = get_blocks()[0] # assuming one block if player[0] < block[0]: move_right() elif player[0] > block[0]: move_left() elif player[1] < block[1]: move_down() # depending on coordinate system elif player[1] > block[1]: move_up() # When adjacent, push toward goal... I get it. You’re tired, the deadline is tomorrow, and you just want the Activity 4.3.1 Terminus Part 2 answer key as a PDF. But here’s the secret: The exam uses similar
This activity is famous for being a “level-up” moment in the course. It’s where the puzzles get genuinely tricky, and the word “Answer Key” starts getting searched for in a panic. I get it
So use the walkthroughs. Look at GitHub examples. But type every line yourself, change the variable names, and test it. That’s real learning.

Before I share where to find the solutions (and how to understand them), let’s be clear:
