BIO

I am a fully qualified Science teacher with specialism in Chemistry. I teach Chemistry from KS3, GCSE up to A-level. I have taught students on numerous exam boards including AQA, OCR, Edexcel and WJEC.

I am also a Chemistry examiner for Edexcel. I studied at the University of Cambridge for my undergraduate degree, Masters degree and a PhD in Chemistry. My specialism has been Chemistry through out.

I am an experienced teacher with enthusiasm and commitment to make chemistry clear and interesting to all students regardless of their background.

My lessons focus on assisting with the development of ideas and arguments that can be applied with clarity to exam questions. I am particularly adept at helping students with their analytical skills, enabling them to showcase convincing judgements to examiners as well as perfecting their exam structure.

I encourage engagement in my lessons and wish to provide a space where students feel comfortable to ask questions or say they are unsure.

Through continual praise and encouragement, I am well suited to be able to help students that are anxious or cannot grasp areas of their subjects. I provide a plan of action for going forward and keep parents consulted on their child’s progress.

I am also happy to set homework questions to build upon the skills covered in the lessons and will mark and give feedback on any work completed.

The platforms I use to teach online are Zoom and Microsoft teams.

The ability to experience each student’s progress at every stage is incredibly rewarding and a wonderful part of my role as a tutor.

I look forward to teaching your son/daughter!

Alberto - London

I’d especially like Thank the Science teacher Miss Aisha Bibi, who has been absolutely outstanding. Her teaching style was clear, structured, and incredibly effective. Her explanations, patient approach, and ability to make complex topics easy to understand have made a world of difference. She breaks down difficult GCSE Science topics in a way that makes them easier to grasp, and always takes the time to ensure the topic is understood before moving on Since joining the centre, my child’s confidence in all 3 Sciences had grown tremendously. He had gone from feeling overwhelmed to tackling exam papers with ease — and it’s reflected in his final GCSE Science results. I highly recommend Aisha to any parent looking for quality Science teacher. Thank you so much!

Verbena - Chelmsford

My Daughter was Tutored by Aisha (Science Tutor), whose been amazing. Initially she had little or no confidence in her ability to achieve GCSE level and had lost interest in the subjects. Aisha took her on and her teaching style was perfect in building up my daughter's confidence, so much so she went from Grade 3 to achieving Grade 8 in all 3 Science subjects. Aisha was patient, compassionate, flexible in adapting her teaching style and pace to suit my daughter's needs. She's very skilled in breaking down the subjects to student level so they can grasp the concepts whilst maintaining their interests. I would highly recommend her for bringing out the best in any student to the highest level.

Ata - Thurrock

Allow me to thank Sue Schulkins for the wonderful work she has done with our son’s English classes. We have seen our son’s interest grow as the sessions have progressed. Before Sue started out with him - I noticed she gathered as much information as she could and she listened to us and even adopted some of our methods. She improved on them and added her own unique creativity. She was very unlike some teachers who would insist on using their own method - she never did that. She was able to find out from our son his expectations and discovered he loves unusually funny narratives. She incorporated this into her curriculum and we have seen such a marked improvement in his English comprehension. He is having fun during the English sessions and his work has improved. He is attentive and focused. Sue Schulkins is certainly a different kind of teacher and we are very happy with her work. Well done Sue.

Sneha - London

My son worked with Katie Jackson for his GCSE Combined Science ( Biology, Chemistry, and Physics) and it made a real difference. The lessons were engaging and helped him get much more confident with tricky topics and exam-style questions. Katie was patient, encouraging, and explained things clearly, which really suited his learning style. He went on to achieve a grade 7, and we’re very pleased with his progress. It was a really positive and supportive experience. I highly recommend Katie to anyone looking for Science teacher.

She really made Maths very easy for him such that he has now considered taking Maths for her A-level.

Christine is an exceptional tutor, she really takes her time to ensure that the child understands her well. I signed up for online sessions with Science Clinic and allocated her to teach my son Sciences, her lessons are so well structured, organised and affordable. I managed to sign up for Maths as well in the end. You are not locked into a contract like what a lot of tutoring companies i used in the past do. I will highly recommend this company to anyone looking for a similar service. If Christine will be available, please ask them to allocate her to teach Science to your child.

Dajana Dala is a really lovely, kind tutor who helped me so much in maths as I started understanding and enjoying maths when I used to hate it and get low grades. She is always ensuring I understand the work and if I don’t she will make sure to help me through different ways and tricks so I understand. Thanks to Dajana, my grades have improved and I actually feel like I’m prepared for my exams. I’d highly recommend her to anyone looking for a skilled, reliable, and encouraging math tutor.

Hello Science Clinic Team, Just wanted to thank your tutors for all their help and support they gave my son, the academic transformation within that short space of time was amazing, there is no way Tade would have achieved the grades he got without your help.....all his tutors were fantastic especially Ms Iqra Shah who was exceptionally good, her resounding knowledge of Science has truly transformed my son within weeks Tade was looking forward to her lessons. I know my wife has given a review on your website, I just wanted to send you a personal text to express my gratitude, I'm sure in years to come, Tade will look back with gratitude for the role Ms Shah played in his life....my wife has referred you and your company to some of her friends and will continue to do so. Thank you once again for time you dedicated to my son.

My daughter received science and maths tuition from Nada whilst studying for her A levels. My daughter benefited hugely from Nada’s enthusiasm and energy, as well as her knowledge of sciences in particular. Nada improved exam question answering technique and enhanced my daughter’s understanding of more complex topics. Crucially Nada instilled confidence and reassurance and always went the extra mile to help.

I couldn’t fault my daughter’s tutor Holly, Holly made the lessons enjoyable, productive and she really listened to my daughter in terms of where she felt she had gaps in her knowledge. She really looked forward to her weekly lessons, and I know it helped her to achieve the high grades she recently received for her GCSE results. Holly’s support and guidance was extremely valuable.
