Hello aspirant!

As far as  my knowledge is concerned you should not think about MCA if you look at your study background then you will get to know that you have completed your bachelor's degree in electronics which is Bsc Honours electronics, and MCA stands for master of computer application which is a completely different field from BSc electronics

Like you have studied about the basics of electronics and their fundamentals in Bsc (h) electronics but if you really want to pursue a master's degree then you can go with MSc e for MTech in electronics there are some reasons behind that one of them is that when you go for an interview and you will be asked why did you choose MCA after BSc electronics and you won't find any answer at that time because it is not relevant to your BSc stream and if you are thinking about the placements then it is useless because after completing Mtech for MSc in electronics you will get a high paid job as there are many recruiting companies for electronics students like NTPC RRB ,BHEL, TCS TECH MAHINDRA, IBM , GODREJ ,LG,SAMSUNG ,SONY etc 

And average package after completing your masters in electronics is approx 4 to 5 lakh per annum if you perdue your  Mtech from a reputed college

Hope I have resolved your well in case of any other doubt you can get back to us
