Does Siksha Sarovar have an AI chatbot to answer student doubts?

Yes. Siksha Sarovar has a built-in AI Assistant chatbot accessible from a floating button on every page. It understands English, Hindi and Hinglish, handles typos (for example 'pyhtion' or 'certifecate'), and indexes 165+ destinations including every course, lesson, BCA subject, school chapter, competitive exam topic, FAQ and tool. Most queries return direct link cards in under 5 milliseconds. An AI fallback is available for novel questions.

Can I ask the SikshaSarovar chatbot questions in Hindi or Hinglish?

Absolutely. The chatbot is built specifically for Indian students — natural Hinglish queries like 'kaise milega certificate', 'free hai kya', 'pyhtion ke datatype kaha hai', 'kaha se shuru karu' are first-class citizens. The matcher strips Hindi filler words and routes you to the right course, lesson or page.

Is the SikshaSarovar AI chatbot free to use?

Yes. The chatbot is 100% free, requires no signup, and is available on every page. It runs locally in your browser for the vast majority of queries — there is no API cost or usage limit. The optional 'Ask AI' fallback for advanced coding questions uses the Pro AI Tutor.

Is Siksha Sarovar really free?

Yes. Every course, lesson, quiz, online compiler, and notes download is free to use without an account. We offer an optional Pro pass that unlocks longer AI tutor sessions, larger compiler quotas and priority support, but it is not required to learn from the platform. The educational content itself stays free.

Do I need to sign in to use the courses?

No. You can browse any course, read all lessons, run code in the compiler and take quizzes without signing in. Google Sign-In is purely optional and is used only to save your progress, quiz scores and certificate eligibility across devices. We never request access to Gmail, Drive, Calendar, Contacts, or any sensitive Google data.

Are the certificates from Siksha Sarovar recognised?

Our certificates are a record of completion that you can share on LinkedIn or attach to applications, but Siksha Sarovar is an independent platform — not a UGC-recognised university or board. We are upfront about that. The certificate is most useful as a verifiable signal that you have completed the curriculum, not as a substitute for a degree.

Which courses are best for BCA and MCA students?

Our University Curriculum section covers the YMCA BCA/MCA syllabus subject-by-subject — Data Structures, DBMS, Web Based Programming, Computer Networks, Operating Systems, Software Engineering, Data Warehousing and more. Each subject is broken down into the same units your university teaches, with previous year question papers where available.

Can I use Siksha Sarovar to prepare for SSC, UPSC, Banking or Railway exams?

Yes. The Competitive section has dedicated tracks for SSC (CGL, CHSL, MTS), UPSC, IBPS/SBI Banking, RRB Railways and defence exams (NDA, CDS, AFCAT). Topics include quantitative aptitude, reasoning, English grammar, general knowledge and current affairs, written specifically for the Indian exam pattern.

What languages does the online compiler support?

The Siksha Sarovar online compiler supports C, C++, Python, Java, PHP, JavaScript, C# and SQL. The compiler runs your code in a sandboxed environment using Judge0, returns the standard output and error stream, and supports stdin so you can test interactive programs. There is no installation — everything runs in your browser.

How is my personal data handled by Siksha Sarovar?

We follow data minimisation: we collect only what is needed (email, name, profile picture from Google sign-in, and your learning progress). Data is stored on Supabase with HTTPS in transit. We do not sell user data, and we do not use it to train AI models. You can request deletion at any time by emailing contact@sikshasarovar.com — see our Privacy Policy for the full details.

Who founded Siksha Sarovar?

4.7 Using Slicers & Syncing Across Pages — Power BI Notes

Lesson 38 of 62 in the free Power BI notes on Siksha Sarovar, written by Rohit Jangra.

Using Slicers in Power BI

Slicers are visual filters placed directly on the report canvas. They provide an intuitive, user-friendly way to filter data interactively.

What is a Slicer?

A slicer is a standalone visual that filters other visuals on the page. Unlike the filter pane, slicers are visible and interactive on the canvas.

Types of Slicers

Slicer Type	Best For	Description
List Slicer	Categories, text values	Displays a list of values with checkboxes
Dropdown Slicer	Saving space	Compact dropdown selection
Date Slicer	Date ranges	Calendar or slider for date selection
Numeric Range Slicer	Number ranges	Slider to set min/max values
Relative Date Slicer	Dynamic dates	"Last 7 days", "Last month", etc.
Tile Slicer	Visual categories	Button-style tiles
Image Slicer	Visual selection	Uses images as slicer options

Creating a Slicer

Steps:

Click an empty area on the canvas
In Visualizations pane → Select the Slicer visual
Drag a field from the Fields pane into the slicer
Configure the slicer style:

Click the Format icon → Slicer settings → Choose: List, Dropdown, or Tile

Date Slicer Configuration

Date slicer styles: • Between — slider to select a date range • Before — show data before a selected date • After — show data after a selected date • List — show dates as checkboxes • Dropdown — compact date list • Relative Date — "Last N days/weeks/months" (dynamically updates)

Multi-Select Options

Single Select: • Click one item at a time (Ctrl+Click for multiple) • Enable in Format → Selection → Single Select: On

Select All: • Add a "Select All" option at the top • Format → Selection → Show "Select All" option: On

Syncing Slicers Across Pages

By default, a slicer only affects the page it's on. You can sync slicers so they affect multiple pages.

Steps to Sync Slicers:

Select the slicer
Go to View → Sync slicers (opens the sync pane)
For each page, configure two options:

Sync (🔗): Should this page respond to the slicer?
Visible (👁️): Should the slicer be visible on this page?

Sync Configurations:

Config	Sync?	Visible?	Effect
Sync + Visible	✅	✅	Slicer appears and filters on this page
Sync + Hidden	✅	❌	Slicer filters this page but isn't shown
No Sync + Visible	❌	✅	Slicer appears but doesn't filter this page
No Sync + Hidden	❌	❌	Slicer has no effect on this page

Advanced Sync Groups: • Create named sync groups to link specific slicers together • Useful when multiple slicers control different dimensions across pages

Best Practices for Slicers

• Use dropdown slicers to save canvas space • Use relative date slicers for time-sensitive dashboards • Sync important slicers (like Date) across all pages • Limit to 3-5 slicers per page to avoid overwhelming users • Place slicers in a consistent location (top or left side) • Use horizontal slicers for fewer options, vertical for many • Set default selections to show the most relevant data initially
