EEE: Electrical and Electronics Engineering branch deals with Electrical technology and machines, circuit analysis, electronics, electromagnetism, electrical engineering materials, instrumentation, control systems, power engineering and transmission and distribution. 

ECE: This branch mainly deals with analog transmission, basic electronics, solid state devices, microprocessors, digital and analog communication, analog integrated circuits, satellite

ECE has a good scope in the future. An electronic engineer can find a job in the consumer electronics manufacturing organisation, telecommunication and IT industry, healthcare equipment manufacturing organisation, mobile communication(2G,3G,4G), internet technologies, and power electronics industry.

They may also work with computers and electronic equipment in the medical, manufacturing,

It's all depends on your interest. If you are interested in hardware oriented stuffs you should go for ECE.  Whereas CSE will teach you more of programming stuffs, computer architecture, networking and core programming like data structures.

If we talk about the difficulty level then CSE is the most easiest

Here is a difference between CSE & ECE.

ECE focuses more on the circuits- ICs, microprocessors, etc that create the magic behind a working device.Organizations usually hire CSE engineers for the same.

CSE focuses on the languages- Java, C++, Python, the list is endless. That doesn’t mean CSE graduates don’t

It is one of the best  and rapid growing  branch of engineering. The scope for any EC engineer is increasing day by day.
Growing convergence between hardware and software – This is something that electronics engineers have an edge in when compared to Computer Graduates.

There are numerous scopes for

Your rank should be under 2 lakhs to get CSE and ECE branch in JAYPEE Solan in JEE Main exam.
