The econs notes were a very useful study resource to help me revise for exams 🙂
shinyoung kimuwce ’23 | LSE ‘ 26
With The45ers constant guidance throughout my journey in the IBDP, I was able to not only achieve a fantastic score, but develop skills that I now take with me to university and my career. To my tutor Aleksandra, there is no such thing as stupid questions, and her dedication and patience ensures that you walk away with confidence in your understanding of a concept.

If I had to reveal the secret of my success in IB examinations, I cannot underestimate the role of The45ers whose tutoring was instrumental in my successful IB journey, in which I was able to score 7 in Mathematics AA HL and Physics HL. My tutor, Aziz’s exceptional guidance, expertise and dedication played a pivotal role in my academic achievements.
Yazuz SelimIBDP’24
When I first started working with The45ers four months ago, I was scoring 5s and 6s in Mathematics AA HL. Since then, my understanding of the content and my ability to tackle exam-style questions have improved significantly, and my average grade has risen to a 7. What sets my tutor Angad apart is his ability to delve deep into topics and help me understand why something works, rather than just skimming the surface.

I wholeheartedly recommend The45ers to anyone who wants to increase their knowledge, clear the integrated concepts and achieve the top scores in their International Baccalaureate journey. My tutor Sahil's patience is commendable. He has a very soft and sweet approach to teaching which has helped many of our peers understand complicated topics.
Shambhavi Jha IBDP’24
I wholeheartedly recommend The45ers to anyone looking for a tutor who can help them achieve their academic goals. I truly believe that my tutor, Sindhu’s organised notes, attention to detail, and ability to clarify complex topics make her the ideal person to approach for academic assistance.
Sanjana Rajesh IBDP’22
Under The45ers tutorship, I scored an almost perfect score of 44 for my IB exams. Moreover, My tutor Mateen’s credentials as a Cambridge offer holder were incredibly motivating and provided a strong foundation for my university applications.
AnonymousIBDP’24
With The45ers help, I was able to score a 7 in IB Literature HL after struggling with 3s and 4s in my first semester in the subject and was also able to score a 6 in the IB Biology HL course with my tutor, Leila’s, useful tips on studying for the course.
