Physics and chemistry — Lower secondary

The first subject where mathematics becomes a tool serving something else. A pupil weak in algebra discovers their gap here, often abruptly, although the difficulty does not come from physics.

They fail physics because of a maths gap

The pupil understands the phenomenon and freezes when isolating a variable in a formula. The conclusion is that they dislike physics, when the problem is unconsolidated algebra. Reworking the physics chapter achieves nothing: you must go back to the source, in the other subject.

What the tutor does with your child

The tutor explicitly separates the two difficulties: it first checks understanding of the phenomenon without any calculation, then handles the mathematical tool separately. Conflating them loses a pupil who only had one of the two problems.

It changes angle the moment an explanation misses
It leaves the answer to the pupil and stays alongside until they find it
It has the result checked by a second route
It goes back to the missing prerequisite, even one from an earlier year
It keeps the concept open until the pupil restates it in their own words

Parents' questions

Are experiments possible remotely?

Some are, with household materials, and the rest go through filmed experiments and simulations. That is a real limit: handling equipment yourself has no substitute, and we do not claim otherwise. Understanding mechanisms and measurement method, however, can be fully trained.
