Well all the three institutions mentioned by you are quite good, choose any of the three, but don’t make haste about the configuration of the Laptop, immediately you may not require it, get into the inst, spend at least 15-20 days and get to know about the system and then only follow the configuration as per the requirements of the inst,.........there are some other better institutions as well which have joined the race of quality education and better placements,......I suggest to visit the official weblinks of those institutions as well and get to know the kind of facilities being provided, quality of education, level of faculty members, fee structures and placement records, so that youhave an extensive information related to admission process,........These inst are – LBS, College of Engg, Kasargod,.............................Lovely Professional Uni, Phagwara,.....................BITS Pilani
