I have done only Physics and Maths when it comes to sciences in my 10+2. I want to pursue B.Tech or B.E here. Is it possible without Chemistry in 10+2?
Yes you can still pursue B.Tech and can pass through flying colors.
But it readily depends on the branch you want to take admission in. In chemical engineering, environmental engineering you need good base of chemistry whereas if you are doing B.Tech in IT , COE branch you will only have chemistry subject in one semester which you can fairly pass by studying quite hard.
