The CFA Level 1 exam gives you 90 seconds per question. Your TI BA II Plus can save you 10-15 seconds per calculation — that is 20+ minutes across 180 questions. Here are the 7 tricks every candidate should master before August 18.
1. Switch to AOS Mode (Algebraic Operating System)
By default, your BA II Plus uses “Chn” (chain) mode, which calculates strictly left to right. In Chn mode, 2 + 3 x 4 = 20. But in finance, the correct answer is 14 (BODMAS/PEMDAS).
Fix: Press [2nd] [FORMAT], scroll to “Chn,” press [2nd] [SET] to switch to AOS. Now your calculator respects order of operations automatically. No more manual bracketing.
2. Set P/Y to 1 (And Leave It There)
Your calculator defaults to 12 payments per year. This causes silent errors in TVM problems — the calculator assumes monthly compounding when you meant annual.
Fix: Press [2nd] [P/Y], type 1, press [ENTER]. Always adjust N and I/Y manually for semi-annual or monthly problems. Never let the calculator do hidden compounding math.
3. The “2nd CLR TVM” Habit
TVM registers (N, I/Y, PV, PMT, FV) remember your last calculation even after you turn the calculator off. This is the #1 cause of wrong answers on the exam.
Fix: Press [2nd] [CLR TVM] before every new TVM problem. Pressing [CE/C] does NOT clear these registers. Only CLR TVM does.
4. Use the CF Worksheet for NPV and IRR
Stop calculating NPV manually with a formula sheet. The BA II Plus has a dedicated cash flow worksheet.
Steps: Press [CF], press [2nd] [CLR WORK] to clear, enter CF0 (negative for outflow), press [ENTER], press down arrow, enter CF1, frequency, repeat. Then press [NPV], enter discount rate, press [ENTER], press down arrow, press [CPT].
This turns a 3-minute manual calculation into a 30-second worksheet entry.
5. Use the Data Worksheet for Statistics
The CFA exam tests mean, standard deviation, and variance frequently. Your calculator can compute all of these automatically.
Steps: Press [2nd] [DATA] to enter values in X1, X2, etc. Then press [2nd] [STAT] to see results.
- Sx = sample standard deviation (use for returns data)
- sigma_x = population standard deviation (use when you have the full population)
Know which one the question asks for — this is a common trap.
6. Use the Bond Worksheet for Yield and Price
The BA II Plus has a built-in bond worksheet that calculates price, yield, and accrued interest automatically.
Steps: Press [2nd] [BOND]. Enter settlement date (SDT), coupon rate (CPN), redemption value (RDV), and yield or price. Press [CPT] for the unknown.
On the BA II Plus Professional, you can also calculate modified duration directly from the bond worksheet by scrolling to DUR and pressing [CPT].
7. Use STO and RCL for Multi-Step Problems
Stop writing intermediate numbers on scratch paper — it is slow and causes rounding errors.
Steps: Press [STO] [1] to store a value. Press [RCL] [1] to recall it. You have 10 memory slots (0-9).
This is essential for DuPont analysis, WACC calculations, and any problem with 3+ intermediate steps.
Exam-Day Calculator Checklist
- Set decimals to 9 (floating): [2nd] [FORMAT] 9 [ENTER]
- Confirm AOS mode is active
- Confirm P/Y = 1
- Check that “BGN” is NOT showing (unless solving annuity due)
- Bring spare CR2032 battery and small screwdriver
- Bring a backup calculator if you have one
Master your calculator. Master your time. Master the exam.
