Hi @nagaklv ,

• Practice again all lab tasks in the given learning course's instance.
• Practice in your Personal Developer Instance (PDI) //Demo instance

Hello @nagaklv ,

You can start with practicing in Servicenow PDI .  

When you start exploring ServiceNow PDI, begin with understanding the basic platform UI:

• Application Navigator, Banner, Content Frame (UI16)

• Explore Forms and List Views

• Company Branding and changing the Welcome Page

• Context Menu (what it is and its types)

• Breadcrumbs and how they work

Next, move on to data modeling basics:

• Table and Field creation

• Table dependencies and Table Extensions

• Field types

• Views

• Important OOTB tables like User (sys_user), Group (sys_user_group), Role (sys_user_role), Delegations

Once you are comfortable with this, explore core configuration concepts:

• Reference Qualifiers

• Dot-walking

• UI Policies

• Dictionary Overrides

• ACLs

• Priority Lookup

• Difference between Configuration vs Customization

Then understand data movement and backup concepts:

• Update Sets (how to take backup of your work)

• Update Set transfer methods

• Import Sets

After learning these basics, you can confidently move forward to explore Service Management modules like:

• Incident

• Problem

• Change

• Request

And then deep dive into the Development part.

Then  start with Certified System Administrator (CSA) – First & Mandatory

• CSA is the basic and most important certification for ServiceNow beginners

• It helps you understand how the ServiceNow platform works

Main topics to focus on:

• Platform UI and navigation

• Tables, fields, forms, and list views

• Users, groups, and roles

• Basic ITSM concepts

• UI Policies, Client Scripts, and Business Rules (basic understanding)

Best practices:

• Practice each topic in your Personal Developer Instance (PDI)

• Do not just memorize answers—try to understand why a feature is used and when to use it

If this helps you then mark it as helpful and accept as solution.

Regards,

Aditya
