LATEST GEL NAIL SPECIALIST
CERTIFICATION EXAM | Q&A WITH
RATIONALES
1. What is the primary chemical process that hardens
gel nail products when exposed to UV or LED light?
A) Oxidation
B) Polymerization
C) Hydrolysis
D) Fermentation
Correct answer: B
Rationale: Polymerization is the chemical reaction
where monomers and oligomers link together to form
a solid polymer network, hardening the gel.
2. Which component of gel polish is activated by UV
or LED light to initiate the curing process?
A) Oligomer
B) Monomer
C) Photoinitiator
D) Polymer
Correct answer: C
,Rationale: The photoinitiator absorbs light energy
and converts it into the energy needed to start the
polymerization process.
3. What is the main difference between hard gel and
soak-off gel?
A) Hard gel requires UV curing; soak-off gel does not
B) Soak-off gel can be removed with acetone; hard
gel must be filed off
C) Hard gel is weaker than soak-off gel
D) Soak-off gel is only used for natural nails
Correct answer: B
Rationale: Soak-off gels can be dissolved in acetone,
while hard gels are non-porous and must be
mechanically filed off.
4. Which of the following is the correct order of
application for a standard gel manicure?
A) Base coat, color coat, top coat
B) Color coat, base coat, top coat
C) Top coat, base coat, color coat
D) Base coat, top coat, color coat
Correct answer: A
,Rationale: The standard sequence is base coat for
adhesion, followed by color coat(s), and finished with
top coat for shine and protection.
5. What is the purpose of capping the free edge
during gel polish application?
A) To add length to the nail
B) To prevent shrinkage and lifting
C) To increase curing speed
D) To remove the inhibition layer
Correct answer: B
Rationale: Capping the free edge seals the nail tip,
preventing the gel from shrinking and lifting away
from the edge.
6. What is the recommended cure time for most gel
polishes under an LED lamp?
A) 10-15 seconds
B) 30-60 seconds
C) 2-3 minutes
D) 5-10 minutes
Correct answer: B
, Rationale: Most gel polishes cure in 30-60 seconds
under an LED lamp, compared to 2-3 minutes under a
UV lamp.
7. What is the inhibition (sticky) layer that remains
after curing gel polish?
A) A layer of uncured polymer that must be wiped off
with cleanser
B) A protective coating that should remain on the nail
C) A sign that the gel was not cured properly
D) A layer of base coat that was applied too thickly
Correct answer: A
Rationale: The inhibition layer is the uncured surface
layer that forms during curing and must be removed
with a cleanser or alcohol wipe.
8. Which of the following best describes the function
of a builder gel?
A) To add shine and protection
B) To add strength and structure to the nail
C) To remove the natural nail's oil
D) To cure the gel polish faster
Correct answer: B
