Donal tutored my son for Common Entrance maths. He was really fantastic: patient, kind, excellent at explaining concepts. My son improved enormously in confidence and skill under Donal and gained much higher grades than predicted at first. We would recommend Donal to anyone looking for a smart, clear, empathetic tutor.

My son was tutored by Omar Gonga, a Maths graduate from Imperial, for his entrance exam into a private school. Omar was very calm, considerate and caring when it came to dealing with my son. He was engaging and dealt with difficult concepts patiently. When my son became bored or irate, he patiently guided him to do his best. The ultimate result was my son passing his entrance exam and doing very well communicating with the deputy head teacher. Thank you so much to Omar and Keystone Tutors for helping my son. A great company with the best tutors.

Dr Lampus is an excellent Chemistry tutor, he is helping my daughter towards achieving a top grade in her A level; he is always positive, approachable, and patient and prepared to help her with any query she might have. My daughter thoroughly enjoys the lessons and I am very grateful for his help and experience at such an important period of her life.

We have been extremely happy with Keystone Tutors. Based on our specific needs, they have managed to find the perfect teacher for our daughter who is doing the IB diploma. The service has been spot on. The teacher is caring, attentive, knowledgable which gives us parents the sense of trust. Can’t recommend them more.

Our experience with Keystone Tutors, specifically Nicky, has been very positive. Nicky has been tutoring my now Year 4 son for over 2 years in phonics and more recently maths. She is incredibly kind, patient, supportive and very engaging. Our son leaves each session with a smile on his face and more confidence. I wouldn’t hesitate to recommend Nicky.
