A is ADMIT you're a sinner, that you need Christ as your savior, and that all those who call on the Lord Jesus and obey Him will be saved. You can't be saved without Him, nor add to or take from what Christ has done for you (Romans 3:23, 5:8, 6:23).
B is BELIEVE the Lord Jesus Christ is the Son of the Living God. You can know He is Who He says He is by the hundreds of prophecies that came true in His Life. Many things foretold hundreds of years before His birth came true in His lifetime, and others He Himself made came true later (Romans 10:9, 10:10).
C is CONFESS to the Lord and admit to yourself that you have responsibilities and that you have commitments as a believer and follower of Jesus Christ. The more you know about the Lord Jesus Christ, the more you'll want to tell other people about Him (Romans 10:13, 11:36, John 1:1).
For any plan of salvation to be effective you need to be in the Bible, God's Word, daily. You can't teach something you don't know. If someone asks you a question you don't know the answer to, that's okay. Find out the answer and get back to them. The important thing is to tell them the difference Christ has made in your life. Lead them through the sinner's prayer below, an example of which is this from sbc.net (keeping in mind that the prayer itself isn't what saves you):
"Lord Jesus, I know that I am a sinner, and that I do not deserve eternal life. But, I believe you died and rose from the grave to purchase a place in Heaven for me. Jesus come into my life, take control of my life, forgive my sins and save me. I am now placing my trust in you alone for my salvation and I accept your free gift of eternal life."
Your Pastor or another believer who has been in the faith for a reasonable amount of time can counsel you, and please remember that new believers need to be discipled. Get them into a good, Christ-centered church, and help them through the trials that always come to new believers. Satan will almost certainly begin to attack them, and they can easily be led into "diverse and strange doctrines." God bless you.
