What should I do if I can’t afford a new laptop for my college learning? My parents are troubled to buy new laptops financially.

Nowadays, you can buy a laptop on EMIs, which will allow you to go for the device of your choice at fairly low monthly EMIs. HP for instance, offers a lot of deals of low cost EMIs on its online store. The other option is to rent a device. There’s a site called Lease with ease, which provides you laptops with the latest hardware on low monthly rentals.
