Maths tutor, Founder(CrystalSurge) (Jul, 2006–Present) at crystalSurge
Founder,CEO and Math tutor at CrystalSurge online tutoring academy and also working as a freelancer.
I have vast experience of 12+ years as an ONLINE Math tutor in various platforms .
I'm running my own Online teaching academy called CrystalSurge.
We believe that neither students nor curriculums are the problems. The lack of skill to understand the particular subject is always the problem. Our specialists assess each student`s skill set for the course, identify the problem and we start working on it. We arrange tutoring sessions that develop the lacking skill and reinforce the material that the student is currently covering. We are able to teach junior and senior students with a mild and kind teaching approach. Our teaching methodology brings the best out of each student.We understand urgencies like school tests, assignments, etc. and we are very flexible to help the student as per their needs. With MQube Tuitions, you can see the difficult subjects transforming into the favorites. Improvement in grades follow.Smiles are shared in the form of positive feedbacks and appreciation. We are thankful to our students and their parents to share the same with us in abundance

A wonderful tutor who goes above and beyond
I’ve had an amazing experience learning at Crystal Surge academy. Tutor Rube is incredibly knowledgeable, patient, and passionate about teaching. Her way of explaining concepts is clear and effective, making even the most difficult topics easy to understand. The academy is well-organized, with a supportive learning environment and great resources. I’ve seen real improvement in my kids confidence and performance since joining. Highly recommended for anyone looking for quality education and personal attention!We took sessions for A level Maths , Chemistry and Physcis from her and her tutors .

Passionate teaching style
I took Ms Rube's online teaching services for my two kids for grade 11 and 12 CBSE board. Rube Ma'am handled my kids really well and she took real pain to understand the learning pain points and addressed them quite well. An inspiring educator who goes above and beyond to make complex concepts accessible, fostering a positive and engaging learning environment for students.
