RubanTools brings together 17 free education utilities in one place - from GPA and SGPA calculators aligned with CBSE and university grading norms to study timers, timetable generators, and resume builders.
India follows diverse grading systems - the 10-point CGPA used by CBSE schools, the semester-based SGPA common in engineering colleges affiliated with Anna University, VTU, and Mumbai University, and the percentage system still preferred by many state boards. Our GPA and SGPA calculators handle all these formats. The exam age eligibility tool helps aspirants quickly verify whether they qualify for UPSC Civil Services (minimum 21 years), SSC exams, or state PSC recruitments based on official cut-off dates.
Beyond calculators, students benefit from structured study tools. The Pomodoro-style study timer helps maintain focus during long preparation sessions - a technique now recommended by several IIT coaching institutes. The MCQ and question paper generator assists teachers in creating practice sets aligned with NCERT chapters. Whether you are targeting IIT-JEE 2026 or your Class 12 boards, these tools are free, mobile-friendly, and designed for Indian students.
