Friendly, experienced tutor, committed to improving your grades.

Sayeed is a Physical Natural Sciences undergraduate at the University of Cambridge. Having studied Physics, Mathematics, Chemistry and Materials Sciences in his first years at university, he is currently specialised in Chemistry with a focus on physical and theoretical fields. Sayeed has completed two summer research internships in nano-chemistry and techno-economic modelling. Brought up in the UK, Sayeed achieved an excellent set of grades for A-Levels (4xA*) and GCSEs (1x9, 2x8, 7xA*, 1xA). His success can be attributed to proper understanding of course content and effective revision techniques. This informs Sayeed’s teaching style of guiding his students through new material by engaging their curiosity and intuition. In this way, students take a personal approach to their learning, rather than relying on rote memorisation. Outside of his studies, Sayeed has taken an active role in several student societies including Access, Welfare, and Charity Officer at the Cambridge University Islamic Society; and Treasurer at the Cambridge University Bangla Society. Sayeed has also taken intermediate-level French and Arabic courses at university and abroad, respectively. His hobbies include hiking and travelling.

Graduate from UCL. Really enjoy tutoring and helping others

Hi :) I'm Alisha. Ive been told that I am an individual who has a positive can do attitude and easy going. You can let me know if this is true ? I've been tutoring for almost 9 years now and absolutely enjoy it. Especially knowing that I'm helping students to build a strong foundation to set them up for the future. I have tutored students from KS1 upto A-levels, teaching Maths and Sciences (and English to younger students). Not only have I tutored students, I have had the amazing opportunity (and a challenging yet unique experience) to also home school a number of students in the past. Misc: I am a socially active person who enjoys trying out new activities or visiting new places. Next on the to do list is sky diving (ahhhh). I also try to be actively involved in raising funds for different charities. For example, I have helped organise charity events to raise funds for educational resources and schools in rural developing countries and orphans in need.

Second year dental student, happy to help :)

Hi, my name is Abdur and I’m currently studying Dentistry at the University of Bristol. I’d describe myself as a kind and friendly person who loves to teach using evidence-based techniques. As a dental student, a lot of my time is spent learning but also teaching others as it reinforces the knowledge I’ve gained from lectures, seminars and clinical sessions. I’d describing my style of teaching as interactive and personal as everyone has their own way of grasping topics. What sets my teaching apart from others is that it integrates core topics and links the common themes which cements the information to a deeper level of understanding. This is something I’ve used in my own studies which has helped me to ranked in the top 10 for the end of Year 1 exams and over achieve over 70% in end of Year 2 exams. I have been tutoring and mentoring students since 2016. What I’ve learnt from this experience is that building confidence in students is one of the key components to boosting grades. I highlight strengths and weaknesses so we can reinforce the areas which require more attention. This is through evidence-based teaching called active recall. The purpose of this method is to stimulate the mind through questioning rather than passive learning. Passive learning is something many students are guilty of which often leads to average grades. Through active learning it highlights areas that requires more attention. Spaced repetition will help to prevent forgetting important information and enables long term storage of knowledge which is crucial for exams!
