Hello,
.
CCE and CSE are similar at a point. CCE is the combination of CCE and CSE you will learn the main things in CCE which covers both the courses whereas CSE is a course which only studies about computational subjects in depth. You will going deep with the subject
.
Now, CCE is said tuff because it cover computer as well as science subjects. Where CSE covers only science subject in depth.
.
Now, CCE is said to have no much jobs and placements according to job sensus.  so better go for CSE branch for not getting a trouble in future
