btech

Does anyone know what Sunstone does? My cousin wanted to pursue BTech in an "X" university and yesterday he received a call from Sunstone and they said that they will get a seat for him in the "X" university in BTech program but he needs to book the seat today by paying a token amount of 10K...

please suggest a fine laptop for a btech student expecting FHD screen (brightness >= 250 nits) 8 gb ram (expandable to 16 gb) 512 gb or 256 gb ssd (expandable) windows + ms office pre-installed c port charging , hdmi out, 3 usb ports a well known brand ... Thank You
