Hi, I want to make an edit in my review. Initially i thought they are not responsive and closed always. But they are very kind and my own brother studied for the past months on a piping course. He is an Mechanical Engg fresher. Our family first told him not to join but later we regret how wrong we are. They taught him well and now he got selected in a startup company... May be some other have bad experience but luckily we got good experience with them.
