Firstly, no course is as such tough for Girls.

In General, Electrical Engineering has a much theoretical and stricter curriculum than ECE in most Engineering Institutes. Electronics has a comparatively relaxed curriculum, somewhat between CSE and EE.

As far as Placement Prospects are concerned, CSE followed by ECE as well as IT and EE have the best Placements in most Engineering Institutes. An added advantage with Electronics is that you can find opportunities in literally any sector, be it the Private Sector with Companies like Jio, Intel, Texas Instruments, Cisco, Qualcomm, Micron, Tata Motors, Infosys, IBM or the Public Sector with BHEL, BEL, TRAI, ISRO and DRDO. You can even go for a Masters or PhD, as Electronics has excellent research interests like Nanoelectronics, Semiconductor Technology, Automation and Robotics, Electronic Material and so on.
