Software Engineering

There is no prerequisite to learn manual testing but an understanding of basics of computer and information technology is good. For manual testing, you also require good domain knowledge such as Finance, healthcare, etc. In order to learn testing automation, you require strong programming expertize in at least one programming and scripting language.

Yes, both are different from each other but CS branch is on top of all other branches of engineering and is a "job giving branch" you can say that.

Hii Hrithik,
Please mention your JEE advance marks as the admissions are done on the basis of JEE.

Hi Ashish,
The salary of a software engineer is 2.17 to 8.18 lakhs per annum.

Chemistry comes as a basic subject of general study in your first year of course of engineering if you go for almost all engineering courses. But, there isn't much to worry about its just the basic things you have learned in your 11th and 12th that's just freshened up with a little more of knowledge which is never too much to care about. So, if you've got your NCERT books. That's more than enough for the most of the chemistry, you'll learn.

Hello Naveen,
You can pursue MCA.
But,
You can not become software engineer unless you have passed your 12th class with compulsory subjects like physics and mathematics.
You can join MCA only if you have studied maths /business maths /statistics in your class 12th plus you are graduate in any discipline from recognized university.
MCA (Masters in computer application) is 2/3 year degree course offered by many university.
If you want to study MCA, you have to clear the entrance examination conduct by reputed institutions.
Good luck.

First be very clear whether you want to go for BCA or B.Tech as for B.Tech you need to have physics, chemistry and maths as compulsory subjects and even for BCA, some colleges demand maths as a compulsory subject.
