There are two types of punishment after death: temporal (temporary) and eternal. If a person dies with just one "mortal" sin on his soul he will be condemned to Hell for eternity. If he dies with only "venial" sins on his soul he will be sent to Purgatory, perhaps for millions of years.
Purgatory is exactly like Hell except that it doesn't last forever. Eventually, the person will be released and enter heaven.

3 True/False Questions
We are justified (saved) by faith alone, not by good works. Good works will result in greater rewards in the afterlife but have no effect on getting saved. This "faith" means relying on Jesus' sacrifice as full atonement for our sins and trusting in God enough to try to live as he said to live. It is not mere intellectual belief in a set of facts. → CATHOLIC
When a person gets baptized his "original sin" is forgiven and God gives him some grace. This grace enables him to do good works. God appreciates the good works and rewards them with more grace. Because the Christian has more grace, he can now do even better works. This pleases God even more, so He gives even more grace, etc.
The Old and New Testaments are the only sources of Christian doctrine. → CATHOLIC
