What are the different ways to access Udemy courses?

Udemy is a trustworthy online learning platform where you can learn everything about Deep Learning, from the basics to the advanced-level concepts. Here are some top Deep Learning course options for you available at Udemy with not more than 1-day duration and fees ranging between INR 350 and INR 3,500:

You can access Udemy courses on multiple devices, such as desktops, laptops, tablets, and mobile phones. There is no limit to the number of devices on which you can access your Udemy course account. 
However, it is important to note that some features may or may not work or may work differently depending on the device or platform's compatibility. For example, you can customize your learning with reminders and use dark mode on the Udemy app. You can also learn anywhere with offline viewing, Chromecast, and AirPlay. Please check which features you want and access the device accordingly.

The Udemy completion certificates indicate that a learner has completed a course, though they don't qualify as officially accredited participation by any university or professional organization.

They may still be valuable for showing skills on your CV and LinkedIn. Certain employers attest to embarking on self-study initiatives recognizing Udemy courses.

To gain industry-recognized credentials, a student may need to take Certification Examinations with professional/industrial bodies (e.g., AWS, Google, Microsoft) after a particular course with Udemy. 

Yes, you can access Udemy offline, but there are a couple of restrictions:

• Courses are downloadable for offline viewing through the Udemy app on mobile devices.

• They may not be viewed offline directly on a desktop or laptop. However, you may download lectures on these devices with the instructor's approval.

• Udemy Business users may download courses via the app, but restrictions may exist depending on their organization's policies.

Udemy offers a variety of subjects for free, but they come with limitations. Such free courses are mostly video lectures without a completion certificate. Please note that Q&A support from the instructor and direct messaging are usually not possible with free courses. Some of these free courses may be offered for a limited time, after which they may turn into for-pay courses.

You can view free courses by using the search option on Udemy's catalogue and choosing "Free" underpricing.
