Hi there,

Yes anybody can crack any examination. It doesn't matter what their stream is until or unless they have interest in the course or not.

See, it is important to understand the interest because if you donot have interest in what you are currently in then definitely you will not be able to do well in a particular course.

As far as your question, bcom entrance exam can be easily cracked with a good preparation of topics required in the examination.

For a science stream student it will surely be difficult because the concepts of that student are of science related field not of commerce but with practise it will be solved.

Hope this helps you.

Thank !!!
