Can the official CITB HS&E test be taken at home?

CITB's current HS&E booking guidance directs candidates to Pearson Professional Centres or approved Internet Test Centres. A separate online course or remotely invigilated course exam should not be described as the CITB HS&E test.

How to use mock tests effectively

Take a full 50-question mock without checking answers as you go.
Review every wrong answer and every guessed answer.
Track weak topics such as work at height, COSHH, electrical safety or environmental controls.
Retake a different mock after targeted revision.
Aim to score above the minimum several times before your official test.

Are online CSCS mock tests enough on their own?

No practice website can guarantee that you will pass. CITB recommends using current revision materials and provides official publications/apps. FastQual's practice bank is designed as an additional revision layer, not a replacement for official material.
