Answer 1

You can use code bits to solve the practice problems. This won't require you to spend bits. But you won't get any XP.

If you want to earn XP, you can use bits (Sololearn coins) to unlock and solve the practice problems.

But remember that some of the practice problems (even those that require pro version/bits to unlock) are quite basic, e.g. there are practice problems that ask you to print a string or store some numbers in variables and print their sum, product etc.

The minimum amount of bits you need to unlock a practice problem is 60. So use your bits wisely or else you'll soon run out of them.

I had over 2500 bits but I spent them carelessly and now I've only 60 left.

Answer 2

You don't need pro subscription for using code bits
