What must I do to be saved?

The correct answer given today in institute was about as simple as keeping the commandments without creating a super list of to dos
As stated in the article of faith.
1) faith in the Lord, Jesus Christ
2) repentance.
3) baptism by immersion by the proper authority.
4) laying on of hands for bestowal of the Holy Ghost.
5) enduring to the end (which end was clarified as death)
Note that while there are many paths ( over 200 thousand currently ) only one on earth right now has the authority to perform the ordinances needed.    
My Sunday school teacher explained it like this, if you are wanting a ticket to a specific event, you might get to that seat more than one way, but only one person is selling the actual tickets to their venue.
I believe that the church of Jesus Christ of Latter-day Saints is the one true venue. This church is not the only one professing needful truths,. but the only way to properly do 3 and 4, and maybe 2. I don't think you can really repent without a proper baptism. I'll stop now before I get side-tracked.
