While enrolling into these chess  courses on these platforms, you will be getting access to the course material, which has been covered in your specialization after you have paid a definite amount. If you are simply eager to view the contents of the course, we suggest taking up the audit or free trial mode for the courses. So, whilst most courses aren’t accessible for free, certain platforms do present you with an alternative to view them for free if you’re not in favour of buying the assignments or getting graded.
