Hi @coldplays6371 and @Kumar_Narayanan, welcome to the thread! Since your questions are kinda similar, I will reply to both of you here.
Yes, some criteria require access to paid Katalon solutions. In addition to taking advantage of the trial period, you can leverage the Community’s Kudos Rewards Scheme to get access to the Katalon solutions. Detail here: How to get free access to Katalon solutions for the Certification Program?
Hope this helps.
