What is the difference between original constitution and Today’s Constitution in terms of article and schedules?

The original constitution consisted of 395 article (divided into 22 parts) and 8 schedules. Although the last article of the Constitution is Article 395, the total number, as of March 2011 is 448. New articles added through amendments have been inserted in the relevant location in the original constitution. In order not to disturb the original numbering, the new articles are inserted with alphanumberic enumerations. For example, Article 21A pertaining to Right to Education was inserted by the 86th Amendment Act.
