Greetings, I am Dr. Jaspreet Kaur, an Assistant Professor deeply committed to igniting the flames of curiosity and fostering a lifelong passion for learning. With a rich tapestry of teaching experience spanning from science at the foundational levels to advanced Physics and Mathematics at the graduation level, I have witnessed the transformative power of education firsthand. My teaching philosophy revolves around creating interactive and engaging learning environments, where students not only absorb knowledge but also develop a profound connection with the subject matter. Throughout my career, I have consistently achieved outstanding results, with all my students exhibiting significant improvements in their academic performance. Academically, I hold a Doctorate of Philosophy (PhD) in Material Sciences and a Master of Philosophy in Atomic & Radiation Physics from Punjabi University, Patiala. My dedication to education extends beyond the classroom, as evidenced by my volunteer work with Art of Living, where I have embraced the values of service and community engagement. Noteworthy achievements include guiding students to exceptional results, such as Tammana's remarkable score of 98 out of 100 in Maths in the CBSE 12th examination and Abhey's outstanding achievement of 80/85 in AQA GCSE Physics. With a strong foundation in organized teaching methods, effective communication, critical thinking, and teamwork, I am committed to shaping the minds of tomorrow and empowering them to reach their fullest potential.
