This course explains the topics in a very well manner but I can’t practice those concepts since all the projects and exercises are blocked for people who can’t pay the course. So could someone recommend books or webistes with practical projects or homeworks to fill the gap. Thanks in advance 
Hi @iaaron,
One other option you can consider is applying for financial aid to give you access to the labs. You can look here for more info and to see if you qualify: Coursera financial aid
