Having to know some people studying in both these institutions, I can state some details about the colleges I got to know from them. There are some key differences between JNTUH and JNTUH CEH.
JNTUH stands for Jawaharlal Nehru Technological University Hyderabad whereas JNTUH CEH stands for Jawaharlal Nehru Technological University Hyderabad- College of Engineering.
Also the JNTU- H is commonly used to differentiate between the main and the sister universities like JNTUK is for Kakinada, JNTUA is for Anantapur. It is differentiated by the post letter after the main institute’s name.
