Georgia Tech ECON 2105: Principles of Macroeconomics
ECON 2105 covers GDP, inflation, unemployment, economic growth, and monetary and fiscal policy. Like its micro counterpart ECON 2106, it doubles as a social science requirement filler and a core course for business and economics paths at Georgia Tech, drawing large enrollments every term.

What makes it hard
The trap is the same as 2106: by Tech standards it's light, so students shelve it during engineering exam weeks, then meet multiple-choice exams whose model questions (AD-AS shifts, policy chains) are sharper than the lecture pace implied. Reasoning through cause-and-effect chains under time pressure is the actual graded skill.
What you'll cover
- • GDP and economic measurement
- • Inflation and unemployment
- • Aggregate demand and aggregate supply
- • Fiscal policy
- • Monetary policy and the Federal Reserve
- • Economic growth
The ECON 2105 study guide
How to study for Georgia Tech ECON 2105, step by step.
- 1
Give it a fixed slot that survives crunch weeks
The standard way Tech students underperform in ECON 2105 is deprioritizing it when engineering exams stack. A modest weekly slot, held without exception, is the entire strategy.
- 2
Drill the policy cause-and-effect chains
Exam questions walk multi-step chains: the Fed acts, rates move, investment responds, output shifts. Practice writing the full chain for each policy scenario until the sequence is automatic.
- 3
Make AD-AS diagrams mechanical
Shifting the curves and reading off price level and output is the macro counterpart of micro's graph fluency. Sketch every scenario you practice: shock, shift, new equilibrium.
- 4
Simulate the multiple-choice format before each exam
The exams are sharper than the lecture pace suggests, and small wording distinctions decide answers. Timed practice sets, not note review, close that gap.

FAQ
Is ECON 2105 hard at Georgia Tech?
It's among the more manageable courses on a Tech schedule, but the multiple-choice exams test multi-step policy reasoning that cramming handles badly. Steady minimal-dose effort earns a strong grade; neglect during crunch weeks is the standard failure mode.
Should I take ECON 2105 or ECON 2106 first?
Either order works; neither is a prerequisite for the other at the principles level. Many students pick by schedule fit; if you're aiming at economics or business coursework beyond the intro level, you'll end up taking both.
How do I study for ECON 2105 exams?
Practice the cause-and-effect chains in writing, from fiscal or monetary action through to output and price level, and sketch the AD-AS diagram for every scenario. Then work timed multiple-choice sets, since wording distinctions decide more points than concepts do.
