I am a full-time mathematics tutor based in Sheffield, UK providing lessons ONLINE and IN-PERSON helping people better understand mathematics across many levels (GCSE, A-Level, IB, and Undergraduate) and many disciplines (engineering, biology, chemistry, physics, finance, and more).

My Enhanced DBS Check is available to view upon request.

The aim of this website is to provide the necessary details of my tuition services, and to provide excellent resources to help students achieve their target grades or further their understanding at GCSE / IGCSE / A-Level / IAL / IB / AP / Undergraduate levels.

Qualifications & Experience:

  • PhD in Applied Mathematics (Loughborough University, UK, 2025).

    • Specialising in the field of nonlinear waves and fluid dynamics having worked on extending the weakly-nonlinear, weakly-dispersive Korteweg-de Vries equation for small amplitude waves to model moderate-to-large amplitude waves in single- and two-layer fluids, involving MATLAB simulations and symbolic computation on Mathematica.

    • One published academic research paper in a highly accredited journal Wave Motion.

    • Invited talks given at national and international conferences (UK, USA, and Italy).

    • 4-year PhD scholarship was fully funded by the Engineering and Physical Sciences Research Council (EPSRC).

  • Master of Mathematics MMath (1st class) degree (Loughborough University, UK, 2020).

  • GCSEs (2014) and A-Levels (Maths, Further Maths, Business Studies, 2016).

  • Tutoring mathematics for 8+ years, with over 5000 hours of teaching.

    • Tutored students part-time throughout my undergraduate and postgraduate study since 2016.

    • Teaching hours mostly include one-to-one lessons, but also those done in secondary schools as well as university seminars.

    • Enhanced DBS Check is available to view upon request.

  • Hundreds of students taught from various backgrounds across the globe at the following levels:

    • GCSE / IGCSE Maths and Further Maths,

    • A-Level Maths and Further Maths,

    • International A-Level Maths and Further Maths,

    • International Baccalaureate (MYP, AASL, AAHL, AISL, AISL),

    • SQA National 5 Maths,

    • SQA National Higher and Advanced Higher Maths,

    • AP Precalculus, Calculus AB / BC, and Statistics,

    • Undergraduate / Postgraduate study.

  • Over 20,000 contributions online in mathematics forums, such as The Student Room. I am proactively helping those students who may not have access to a tutor whenever I can.

    • I also craft my own material to share with the mathematics community, and some of these questions have gone viral as some of the most difficult (e.g. here, and here).


A Few Testimonials


“Nerijus has allowed me to regain confidence in my mathematical abilities that I had lost a long time ago. Since grade 10, I have not received an adequate level of education, as the teachers at my school would switch up periodically, hence losing track of the syllabus. Nerijus and I had the challenging task of preparing for the IB exams in less than a month. Things would have been much simpler if our lessons were simple revisions, however as I have already stated above, I could not cover most of the syllabus due to the incompetence of my school and its teachers. Nerijus carefully walked me through all of the topics I had no prior knowledge of, explaining everything in detail and giving me tips and shortcuts to the most complex problems and questions. It is truly a shame that our "alliance" in tackling maths had to end at some point; however, I genuinely believe that I will continue using Neri's services in the future. I will refer all of my siblings and friends who are struggling in high school or Uni straight to Nerijus.

If all of my teachers were at least close to Nerijus's professionalism, I would've been able to take Math HL for my diploma and achieve the highest grades!”

— Mikael, an IB AI SL student from Austria


“Nerijus has supported my son weekly since December in building his confidence in some maths topics he has historically struggled to grasp. It's fair to say Maths has never been one of his best topics, but he felt really happy going into his GCSEs with the techniques that Neri had given him. Highly recommend Nerijus if you have a child who lacks confidence in Maths, as he has a kind and patient style that really brought the best out of my son. Thank you!”

— Angi, parent of an IGCSE Maths student from the UK


“Neri was amazing help with preparation for my university exams this last month. He explained everything throughly and really helped me feel confident for the exams. Outside of lesson time he also sent me further resources and questions similar to the ones we did in lessons and if we didn’t have time to go though everything in a lesson he would send me the worked solutions for my specific questions after which was super helpful. Neri had fast replies and very flexible working hours, a really amazing tutor.”

— Isabella, an Undergraduate student from the UK


“I had a brilliant experience with Neri throughout all of the online lessons! He explained concepts clearly, was incredibly patient, and always made sure I fully understood the material before moving on. His teaching style is engaging and supportive, which really boosted my confidence and helped me achieve my goals. Highly recommend to anyone looking for effective and personalized online tutoring!”

— Panagiotis, an Undergraduate student from Cyprus


“I had been struggling with AA HL maths for a while so after my mock exams I decided to seek help from a tutor and found Nerijus. I’ve just given my IB exams and the improvement is evident!! Our lessons have helped me gain confidence in my overall understanding as well as become aware of smaller details that really make the difference. Nerijus is not only very skilled in mathematics, but he can also explain difficult concepts in a way that makes them so much easier to grasp! I would without a doubt recommend him to anyone that is struggling or looking to improve both their understanding and thinking skills.”

— Arianna, an IB AA HL student from Peru


“Neri has been honestly the best tutor I have ever had. He has really helped me grasps the concepts of maths I didn't understand and goes through them step by step- something I truly needed. I don't think I ever came out of a lesson with him not understanding any of the content. Would truly recommend :-)”

— Olivia, an Undergraduate student from the UK
