@Hritik_Moon if you're access a LAB environment for your learning, you may well be using classic compute in there. You could check the Spark UI that way. Alternatively, I think the Community Edition still has some life in it, perhaps you could sign up to it as I think that uses classic compute. 

If not, could you sign up for a Databricks Trial? This should have the ability for you to access non serverless compute. 

Are you learning the Apache Spark Developer Certification by any chance @Hritik_Moon? 🙂

All the best,
