It is the fundamental question over which most of aspiring students ponder a lot
Should i got for this or that
The choice also brings with it confusion
I also went through the same phase once
And from my experience rather than taking guidelines from others you should ask yourself whether what stream you are passionate about every field has oppurtunities you have to explore them and grab them when they come to you moreover ponder upon
You interest lies in which fields
Like you like machines cars go for mechanical
Construction work always captivate you go for civil
Want to know who is behind all softawares in pc and phone go for IT
So it is completely upto you that what you like
Sit down relax and think about your passion your priorities and then your innerself will tell you what you want and you can select stream accordingly
I hope this will be helpful for you
