Data Sufficiency

The art of determining "Is this enough info?"

Coming Soon

1. Check Statement I alone. Sufficient? -> Keep Option A or D.

2. Check Statement II alone. Sufficient? -> Keep Option B or D.

3. If I ✓ and II ✗ -> Answer: I only.

4. If I ✗ and II ✗ -> Check BOTH. If ✓ -> Both. If ✗ -> Neither.

Rule:

1. Check Statement I alone. (T/F) 2. Check Statement II alone. (T/F) 3. If both False, Check I + II combined.

Example:

Never jump to combining first!

Combining too early leads to 'Both' answer when 'I alone' might have worked.
