Make sure that the learning and lab facilities in the centre are efficient by visiting two or three similar institutes. Enquire to previous students about their experiences and opinion. Ask for the copy of certificate issuing from the institute and make sure its authenticity. Institutes which provide courses at low cost might be issuing the certificate in their own letterhead, through which no job will be offered in India or abroad. Study only in institutes where they will offer placement guarantee. Studying in an institution which offers a job with stipend along with studies will become an added advantage by having job experience. Apart from that, it will give a better understanding of the learned theory when it is applied practically.
