Hello Sanaa,

Usually MCA duration is 3 years. Universities offers two type of MCA course. One is MCA-LE this course is for those students who completed their BCA or BSC-IT. If any students done professional graduation in computer or IT then they are eligible for this exam. The students can directly take admission in 2 year. And the course for them will be of 2 years

Second is MCA general this is for the students who have non techincal background and for them duration is of 3 years.

Hope this helps

Good Luck.
