Comments

The candidate’s answers show good understanding of the chemical concepts and principles in the curriculum (e.g. Paper 1 Qs. 1(b), 2(a), 3(b), 4(b), 10(c)(i), 13(d); Paper 2 Qs. 1(a)(ii), 1(a)(iii), 1(b)(i), 1(c)(ii), 3(a)(ii), 3(c)(ii)(2)). He/she demonstrates very good abilities of applying chemical concepts on unfamiliar situations for solving the problems (e.g. Paper 1 Qs. 8(a)(i), 12; Paper 2 Qs. 1(b)(iv)(1), 3(b)(ii)(2)). The candidate performs well on chemical calculations (e.g. Paper 1 Qs. 1(c)(i), 6(b)(ii), 7(d), 10(b); Paper 2 Qs. 1(c)(i), 3(b)(i)(2), 3(b)(ii)(3)). He/she can effectively communicate ideas using scientific terminology, appropriate diagrams and chemical equations (e.g. Paper 1 Qs. 1(c)(ii), 3(c)(i), 6(b)(i), 7(d), 12, 13(a); Paper 2 Q. 1(c)(iii)). He/she can design appropriate method for carrying out scientific investigations (e.g. Paper 1 Qs. 13(a), 13(e); Paper 2 Q. 3(c)(ii)(1)).
