Question 1

What should I focus on for Cambridge OCR Alternative Academic Qualification Applied Science?

Accepted Answer

Always link technique choice to the specific property exploited (e.g. 'distillation because the components have different boiling points'). This shows applied understanding.

Question 2

What should I focus on for Cambridge OCR Alternative Academic Qualification Applied Science? (2)

Accepted Answer

For spectroscopy questions, annotate spectra directly: label key peaks on IR, draw fragments on MS, and use colour-coded integration curves on NMR. Examiners reward visual evidence of interpretation.

Question 3

What should I focus on for Cambridge OCR Alternative Academic Qualification Applied Science? (3)

Accepted Answer

In practical write-ups, detail health and safety considerations explicitly (e.g. wearing goggles, using fume cupboard for volatile solvents). This is a key assessment criterion for vocational qualifications.

Question 4

What should I focus on for Cambridge OCR Alternative Academic Qualification Applied Science? (4)

Accepted Answer

When comparing analytical methods, use a structured approach: name principle, detection limit, cost, time, and give a real-world example (e.g. 'AAS is preferred for low-concentration metal analysis in water samples due to high sensitivity').

Question 5

What should I focus on for Cambridge OCR Alternative Academic Qualification Applied Science? (5)

Accepted Answer

In written assessments, always support descriptions of biological molecules with clear, labelled diagrams and reference to their structure–function relationships.

Question 6

What are common mistakes in Cambridge OCR Alternative Academic Qualification Applied Science?

Accepted Answer

Confusing qualitative and quantitative analysis: students often think a colour change test gives concentration rather than just presence/absence.

Question 7

What are common mistakes in Cambridge OCR Alternative Academic Qualification Applied Science? (2)

Accepted Answer

Misidentifying chromatography Rf values: calculating with wrong units or not accounting for environmental factors affecting results.

Question 8

What are common mistakes in Cambridge OCR Alternative Academic Qualification Applied Science? (3)

Accepted Answer

Misinterpreting NMR splitting patterns, leading to incorrect assignment of adjacent proton numbers.
