The diagram made by the student is correct

Explanation: Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and $\Delta H$ which is difference between energy of products and energy of reactants come out to be positive.

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and $\Delta H$ which is difference between energy of products and energy of reactants comes out to be negative.

Labeling of the parts in the diagram:

X represents the potential energy of the reactants.

Y represents the potential energy of the products.

The energy diagram for an exothermic reaction should have products at a lower energy than the reactants as heat is released.
