Your child understands the idea, then Gateway hands them an unfamiliar reaction or a PAG practical and the marks leak. We match them with a tutor who knows how OCR frames its questions.
A 40-minute consultation about OCR GCSE Chemistry. Joe calls you back within one working day, then sends two or three tutors with free trial calls.
Gateway Chemistry (J248) is two concept-led papers, each 90 marks, with the Practical Activity Groups and practical skills threaded through both. Here is what each paper covers, and where the marks are really decided.
First chemistry paper · C1 to C3, plus C7
1 hour 45 minutes, 90 marks, half the GCSE. Particles, elements compounds and mixtures, and chemical reactions, with the C7 practical skills content assessed alongside. Note the 90-mark total, OCR marks its Gateway papers differently from AQA and Edexcel.
Second chemistry paper · C4 to C6, plus C7
1 hour 45 minutes, 90 marks, the other half. Predicting and identifying reactions and products, monitoring and controlling chemical reactions, and global challenges, with C7 practical skills threaded through again.
The Practical Activity Groups (PAGs)
OCR groups its required practicals into Practical Activity Groups, from making a soluble salt and electrolysis to rates, titration, chromatography and testing for ions. Exam questions pull straight from the PAGs, so a tutor makes sure your child can explain the method and read the results, not just recall the theory.
Concept-led questions
Gateway is built around chemical ideas and how scientists reach them, so questions often ask a child to apply a concept to an unfamiliar reaction or a set of data. A tutor drills the reasoning that turns 'I have never seen this reaction' into the right method on the page.
Where the marks are
Because OCR pulls exam questions straight from the Practical Activity Groups, knowing the method matters as much as knowing the theory. A tutor goes through each PAG, from making a soluble salt to electrolysis, rates and testing for ions, so the practical questions read as familiar.
Gateway is concept-led, so it often hands a child a reaction or a dataset they have never seen and asks them to apply an idea to it. A tutor drills the reasoning that turns an unfamiliar question into the right method, which is exactly where the higher grades are won and lost.
Moles, concentration, electrolysis and rates calculations all appear, and Higher tier carries the heavier maths. A tutor works the numbers inside the chemistry and shows the working OCR wants to see, so a calculation question stops draining marks.
From enquiry to first session
When you get in touch, co-founder Joe calls you back within one working day to fix a time. The call is a proper conversation about your child's OCR Gateway Chemistry, the predicted grade, the mock that came back low and the topics the class moved past too fast. From there he starts building a shortlist.
Joe sends two or three tutors he thinks fit your child, and each offers a free trial call. You watch how they explain a tricky bit of chemistry, and you see who your child actually clicks with. No card details, no pressure, no obligation after.
You pick the tutor who feels right, and weekly sessions start on Lessonspace, our shared online whiteboard. You pay per session, there are no contracts, and if it ever stops working, you stop.
Verified Google reviews
Every review here is verified on Google and left in the family's own words. None of them names Chemistry, so we have not relabelled any as a Chemistry story. What they point to is the thing an OCR Chemistry parent is really after: the grade moving, and a child who stops dreading the paper.
My daughter was struggling with confidence in Maths GCSE and we decided to get a tutor. We were given a selection of tutors to choose from and told that if it did not feel like a good match we could try others. Our tutor was a complete star, listened, made it simple, set good homework and gave my daughter her confidence back. Highly recommend.
Helped me a lot and really showed me what I need to improve on.
Very good tutoring for my daughter and good communication with parents. My daughter passed both English and Maths GCSE.
He will call you back within one working day to set up a 40-minute consultation. He will confirm the route, Gateway or Twenty First Century, then ask about the tier, the predicted grade and the topics slipping, and send two or three tutors with free trial calls. If he does not think tutoring is the right move for now, he will say so.
OCR runs two GCSE routes. Gateway Science A (J248) is the concept-led one this page is about, sat as two chemistry papers of 1 hour 45 minutes and 90 marks each. OCR also runs Twenty First Century B (J258), which is context-led. They are genuinely different, so if you are not certain which one your child is on, Joe pins it down on the first call before any tutor is matched.
PAGs are OCR's Practical Activity Groups, the way it organises the required practicals, from making a soluble salt and electrolysis to rates, titration, chromatography and testing for ions. OCR pulls exam questions straight from them, so the method matters as much as the theory. A tutor goes through each PAG so the practical questions read as familiar.
OCR simply marks its Gateway science papers differently from AQA and Edexcel. Each of the two chemistry papers is 1 hour 45 minutes and 90 marks, and together they make up the full GCSE. It changes nothing about how hard the paper is, but a tutor makes sure your child is practising against real OCR papers and OCR mark schemes, not another board's.
Gateway is built around chemical ideas and how scientists arrive at them, so questions often hand a child an unfamiliar reaction or dataset and ask them to apply a concept to it. That is where bright students freeze. A tutor drills the reasoning that turns 'I have never seen this' into the right method on the page.
More than families expect. Moles, concentration, electrolysis and rates calculations all appear, and Higher tier carries the heavier maths. If rearranging a formula or converting units never quite clicked, it shows up here. A tutor works the numbers inside the chemistry and shows the working OCR wants to see.
Yes. Every session runs on Lessonspace, our shared whiteboard, and it suits chemistry well. The tutor can work through a PAG method, balance an equation and walk a calculation line by line with your child watching every step. Most students focus better one-to-one online than in a class of thirty. We do not do in person.
