Common Traps
CBT 1 merit
CBT 1 screens ≠ CBT 2 ranks
Minimum vs cutoff
Minimum qualifies ≠ Cutoff selects
Wrong vs blank
Wrong loses marks ≠ Blank loses none
CBAT for all
CBAT post-specific ≠ Typing post-specific
Percent base
Profit uses CP ≠ Discount uses marked price
Speed units
Convert before formula ≠ Keep units same
Syllogism certainty
Only must-follow ≠ Ignore possibilities
Current affairs drift
Use current cycle ≠ Avoid stale notes
