Can a prospective Catholic convert skip the RCIA by self-teaching? Main Question: Can a prospective Catholic convert skip the RCIA by self-teaching the entire corpus of the Catechism of the Catholic Church? 

Sub-questions: What parts of the RCIA would the prospective Catholic convert miss out? Would there be a rigorous factual examination of the CCC to confirm that the individual has truly read the material? Also, does the prospective convert really have to believe that the doctrines are true, or will the factual knowledge of the CCC be sufficient for baptism by the Catholic church?
From Code of Canon Law Can.  865 §1., for one to be baptized, one must have been instructed sufficiently about the truths of faith.


  Can.  865 §1. For an adult to be baptized, the person must have
  manifested the intention to receive baptism, have been instructed
  sufficiently about the truths of the faith and Christian
  obligations, and have been tested in the Christian life through the
  catechumenate. The adult is also to be urged to have sorrow for
  personal sins.


This has a basis in Church Tradition and history.

In the early Church those who desired to be baptized and become followers of Jesus engaged in a lengthy period of preparation and instruction.


  In the early Church those who desired to be baptized and become
  followers of Jesus engaged in a lengthy period of preparation and
  instruction. They were called “catechumens” and their process of
  initiation formed them in the ways of discipleship, incorporated them
  into the Christian community and culminated in the sacraments of
  initiation: Baptism, Confirmation, and Eucharist (Holy Communion). In
  recent years the Catholic Church has reclaimed this process now called
  the Rite of Christian Initiation of Adults, often referred to as the
  RCIA process. Initiation is a journey of conversion that is gradual
  and suited to individual needs. It is a process rather than an
  educational program and this process takes place within the community
  of the faithful, the local Church. - Source: A Look at the Christian Initiation Process | Diocese of Manchester.


The Church through her dioceses establishes a norm called RCIA to achieve this.

A good program in fidelity to the Church and her teaching will by must include the Catechism of the Catholic Church.

I am not aware of a program within the Church where a prospective Catholic convert can skip the RCIA by self-teaching the entire corpus of the Catechism of the Catholic Church.

Since skipping RCIA is not an option, the Sub-questions have not been answered.
