One shotting my homework

March 8, 2026

Text to speech fine-tuned locally on my own voice using Coqui, running on my M1 MacBook.

Since my school provides access to OpenAI's models, I swapped my subscription over to Anthropic. I wanted to try out a Chrome extension that lets an agent interact with the browser, and my finance homework seemed like a good test. It was a 10-part quiz where the agent just had to pick multiple choice answers and click next.

The bot basically got all the financial questions right, but failed the reading comprehension. Mostly my fault, as I prompted it as if it was only numeraical finance questions. In the end it got 6 out of 10. Three of the wrong were reading-based, and the last one was a complex task of writing a code snippet and adding a summary, it might've gotten partial credit, but I'm calling it wrong to stay prudent. The bot finished in about 10min, meanwhile it took me an over an hour to check its work. Still I was surprised by some of the questions it nailed.

Question by question breakdown

Q1 — ZAR/HKD cross-rate → C) 0.9205
ZAR/HKD = (CNY/HKD) ÷ (CNY/ZAR) = 0.8422 ÷ 0.9149 = 0.9205

Q2 — Arbitrage opportunity → A) ZAR 6,700 per million SEK traded
Buy SEK cheap at 1.1143 ZAR/SEK, sell at 1.1210 ZAR/SEK → profit = (1.1210 − 1.1143) × 1,000,000 = ZAR 6,700

Q3 — CIP forward rate → B) $1.8961/£
F = 1.8862 × (1.0535/1.0480) = $1.8961/£

Q4 — Foreign currency PV approach → A) $516,000
PV(ARS) = 2,000,000/1.0275 = 1,946,472; × $0.265/ARS ≈ $516,000

Q5 — ESG/CSR COVID-19 resilience → B) 0.09 percentage points
Per the course's ESG literature, a 1 SD increase in CSR score increases weekly stock price by 0.09 ppts. Correct was D—text + search-based question.

Q6 — E&S supply chain transmission → D) None of the above
Literature shows transmission is strongest with higher client bargaining power + lower supplier ESG standards. Correct was A.

Q7 — Actuarially fair insurance premium → A) $8.67 million
r = 5% + (−0.25)(5%) = 3.75%; PV = (2% × $450M)/1.0375 = $8.67M. Impressive.

Q8 — NPV of risk management strategy → D) None of the above
NPV = $80,000/1.05 − $250,000 = −$173,810 (doesn't match A, B, or C)

Q9 — Uganda World Bank Enterprise Survey → D) Medium firms' gift-giving lower than SSA average
Correct was A—needed search.

Q10 — TastyFish profit plot → Chart uploaded
Created and uploaded a chart with all three lines (Unhedged, Forward Hedge, Option Hedge) plus a written summary. Very solid effort, but I'm counting it wrong to be prudent—it was a complex task that might've gotten partial credit.

Total: 6/10


NOTE: I went through every answer in detail. This wasn't me handing it off to AI and calling it done. I probably spent twice as long on the quiz than I would have otherwise, checking everything myself.
