Is there a way to access all code coach challenges without pro?

Question

We can solve only few without pro membership but is there a way to access and solve them without pro membership?

Answer 1

Try challenges from others free websites like
hacker rank
UVA-online judge
...

Answer 2

No

Answer 3

I’m not sure if the competition ended but if you complete all the free challenges they will give you a year worth of pro to the first 100 to complete them all.

Answer 4

Pay monthly is the only way

Answer 5

Ask someone with pro, if he wants to tell you what you have to do in the challenge, maybe.
