All videos and assignments are free on NPTEL and SWAYAM. The certificate is recognised by many Indian universities for credit transfer and by GATE aspirants. Great for GATE and semester exam preparation. Taught by Indian Institute of Technology Madras, one of the strongest names in its field. Completely free. Self-paced: start any time. A clear syllabus (12 parts) you can see before you start. The certificate needs a proctored exam at a centre, which has a fee. Recorded classroom lectures: thorough, but slower than made-for-online courses. New runs start on fixed dates (January and July). Learning is free, but the certificate costs money. Some points apply to every course of this kind; see how we rank .
Free: Every video and assignment is free on NPTEL and SWAYAM. Enrol when the next run opens.Certificate: Optional. It needs a proctored exam at a centre, which has a fee.Taught by Prof.S. Sankaran IIT Madras
