Problem solving on the TSA evaluates numerical agility and logical optimization under tight time constraints (~1.8 minutes per question).

Bottleneck Analysis: In production or scheduling problems, the slowest step determines maximum overall throughput.
Combined Work Rates:
If Machine A completes a job in \(t_A\) hours and Machine B in \(t_B\) hours, combined rate = \(\frac{1}{t_A} + \frac{1}{t_B} = \frac{1}{t_{\text{total}}}\).
Optimization Strategy: Always test boundary cases (minimum and maximum possible values).

Exam strategy

Focus on understanding underlying concepts — exam questions test application, not memorization.
