Before starting career in software industry i would like to ask u r u very much confidant on any of the programming language. Can u independently handle any language? If ur ans comes YES then only think for software development line or testing line. Every line is good only depends upon u how much

You need not do MCA. First it is three years. Even MCA graduates cannot do testing job without training and learning extra. You can do testing certiciate courses and if you have good computer knowledge you can get jobs in testing.
