Two hours, not two months Eight short modules. Finish in a day, or do one module a night for a week.

Skills your degree does not cover Employers ask for practical tools alongside the qualification. This fills that gap while you study.

About two hours in total — eight modules of roughly fifteen minutes. You can do it in one sitting or spread it across a week. Your place is saved either way.
No. There is no prerequisite course and no software to install. A phone, tablet or computer with an internet connection is enough.
Yes. This course is placed at Bachelor's Degree for India, and the content is written for that level. If you are at a different stage, change your level at the top of the page and the courses will change with it.
A certificate for the course, carrying an ID that your college or an employer can check on our verification page. You keep access to the material afterwards.
Yes — ₹450 for this course on its own, or ₹1,450 for all five in this set, which works out cheaper if you want more than one.
There is a short quiz at the end of each module so you can check what stuck. It is not timed and you can retake it.
