Hi f-24,
Allow me to forward some two cents' worth to you. Unless you have a very strong and compelling passion for a certain field (in your case, electronics), don't chance it. Remember the saying which goes something like this, the grass is always greener on the other side? After you have make the switch from photonics to electronics or microE, the grass on the other side might be greener. Who knows?
I was once at your stage too, and I understand how the insecure feeling is. Look at it this way, a degree is a degree, nothing more than that. It will not make yourself a specialist in that field after four years of education. It will just be a blank piece of paper without experience. And you will not be a crackerjack in that field too, unless what you studied coincides with what you work as, something which is occuring very far and few in between.
Let me share some true-life story with you. I was a mechanical engineering student in UniMAP, and after graduation, I was working as a software development engineer. Now that I have left that job, I am now working on material synthesis for Li-ion battery. Did you see any link for what I did as a profession and what I studied as a student? I leave the answer to you.
All in all, don't get too carried away with the so-called passion for something. It's good to have passion, but it's kinda early to talk about it at this time. Unless the paths in front of you are all well and truly paved, you should take it one step at a time.
thanks for sharing me ur story.maybe ure right..we dont know how the future is..
maybe im just too afraid and feels insecure with unimap accreditation problem since my mom always ask me whtr this course can make me work with the government.
