About your coding tutor - Kritika
I'm a software engineer with 3+ years of industry experience and 5+ years of teaching experience. I teach Python, C, C++, C#, HTML, CSS, and JavaScript to school students, college learners, and working professionals. Working in the industry gives me a practical edge: I don't just teach theory, I show how code is actually written and used in real projects. My teaching style is concepts first, then practice. I break down topics like loops, functions, OOP, data structures, and debugging into small, easy steps using real-life examples, so students understand the "why" behind the code and not just the syntax. Every session is hands-on. We write code together, solve problems live, and build small projects, from simple programs to responsive web pages, so students gain real confidence. I'm patient, encouraging, and comfortable with complete beginners. No question is too basic, and I make sure students feel safe making mistakes, because that's how good programmers are made. I also help with homework, assignments, exam preparation, and project work, and I teach students to debug on their own so they become independent problem-solvers. Along the way, I share best practices, shortcuts, and tips from my work experience, and I build a learning plan around each student's goals and pace. Whether you're starting from zero or want to level up for college, interviews, or a career in tech, I'll help you get there.

Coding concepts taught by Kritika
Student and Tutor reviewed essential Excel navigation shortcuts and then delved into advanced lookup and aggregation techniques. They explored the functionalities of `INDEX MATCH` for flexible data retrieval and `SUMPRODUCT` for multi-criteria data aggregation, practicing these concepts with a sales data set. The session concluded with plans for the Tutor to share the sheet for student practice and follow-up discussion.
VLOOKUP Limitations & Why INDEX MATCH is Better
INDEX MATCH for Single-Criteria Lookup
Two-Way Data Aggregation with SUMPRODUCT across Sheets
INDEX MATCH for Two-Way Lookup (Row & Column)
IFERROR for Formula Robustness
Student and Tutor had an in-depth lesson on Microsoft Outlook, covering various functionalities for email management and communication. The Student practiced creating email signatures and contact lists, and learned about search features, email categorization, calendar event scheduling, and automatic replies. They also discussed recalling messages and were advised to practice the learned features before the next session, which will focus on Excel.

& Signatures
Email Organization & Prioritization
The class focused on advanced Excel financial functions, specifically reviewing the Future Value (FV) formula, introducing the Internal Rate of Return (IRR) for investment analysis, and covering common Excel error types with methods to resolve them using `IFERROR` and `ISERROR`. The Student also practiced several key Excel shortcuts for navigation and formatting. For homework, the Student was assigned to practice the learned Excel shortcuts.

Essential Excel Productivity Shortcuts
Handling Excel Errors with IFERROR
Internal Rate of Return (IRR)
Future Value (FV) with Initial Investment
Project Selection using IRR and Hurdle Rate
The Student and Tutor focused on mastering several key Excel functions. They practiced financial calculations using PMT (for loan payments) and FV (for future savings), as well as implementing logical IF conditions for grading and data categorization. The session also covered VLOOKUP for data retrieval, with the Student actively applying these formulas. The plan for the next session is to cover Outlook, and the Tutor will share the current spreadsheet for review.
FV Function: Projecting Future Savings
PMT Function: Calculating Loan Payments
Absolute vs. Relative Cell References ($)
Nested IF Conditions: Dynamic Grading Logic
VLOOKUP: Finding Data in Tables
The Student and Tutor reviewed the VLOOKUP function and then delved into Excel's financial functions, including PMT for calculating loan payments, FV for determining future investment values, and NPV for evaluating business investments. The Student practiced applying these formulas to various real-world scenarios. Homework was assigned to further practice the FV and NPV functions by adjusting key parameters.
VLOOKUP Refresher: Exact Match
PMT Function: Calculating Loan Payments
FV Function: Projecting Future Savings
NPV Function: Evaluating Investment Value
The Student and Tutor worked through Homework Six in R, focusing on data manipulation and statistical analysis. They imported and concatenated SAS datasets, applied complex inclusion/exclusion criteria to filter data, and created various categorical variables. The session culminated in generating a detailed "Table 1" for analysis, and the Student was advised to save the script.
