Hello there!

Greetings!

Yes , cbse gives step marking and  step marking will be there in cbse board exam 2020 as well, so you don't need to worry about this at all.  Cbse follows a marking scheme according to marking scheme fir copy  checking and marking scheme takes care of step marking etc . For example,  if there's a 6 marks question in Mathematics,  you did all the steps right but in the last step you made a calculation mistake and you got a wrong answer,  so in this case you will get at least 4 marks.  So , yes step marking is there in cbse. Prepare well for board exam.
