## What is ThiNail?

ThiNail is a Vietnamese study app for the California and Texas manicurist (nail), esthetician (skin) and cosmetologist (hair) written exams, made for Vietnamese nail and beauty workers in the United States. The app is in Vietnamese; every question is shown in both Vietnamese and English.

READ EVERY QUESTION IN YOUR LANGUAGE
• Vietnamese, English, or both side by side.
• Tap the speaker to hear the question and choices read aloud.
• After you answer: why the correct answer is right, why your choice is not, what to remember, and the source (California 16 CCR; Texas 16 TAC chapter 83 and Occupations Code chapter 1603; ThiNail notes).

WHAT DOES THE EXAM WORDING MEAN?
The Vietnamese version of the PSI exam is translated word by word, so "matrix" becomes "ma trận" instead of "mầm móng". ThiNail's three-column dictionary has 104 terms: English, the PSI Vietnamese wording, and what Vietnamese technicians actually say in the salon. The dictionary is always free.

SIX LICENSES, TWO STATES
California:
• Manicurist: 754 questions, 60 scored questions, 90 minutes.
• Esthetician: 926 questions, 75 scored questions, 90 minutes.
• Cosmetologist: 1,789 questions, 100 scored questions, 120 minutes.
Texas (TDLR):
• Manicurist: 681 questions, 60 scored questions, 90 minutes.
• Esthetician: 782 questions, 75 scored questions, 105 minutes.
• Cosmetology Operator: 1,578 questions, 100 scored questions, 120 minutes.
Questions follow the sections of each state's PSI candidate bulletin. Law and infection control questions are written for each state's own rules.

MOCK EXAMS
10 mock exams per license, plus a 20-question mini exam and random exams. The timer keeps running if you leave the app. Flag questions, jump with the question grid, and see your score by section.

KNOW WHERE YOU STAND
A readiness score from your own answers, with a margin of error, against the state's pass mark (Texas 70% per PSI; an assumed 75% for California). Missed questions come back after 1, 3, 7 and 14 days.

ONE-TIME PURCHASE
No account, no ads, works offline. Each license includes a 10-question check, a mini exam and one full mock exam to try. Unlock a license with a one-time purchase, or get all three licenses of your state.

ThiNail is an independent study tool. It is not affiliated with or endorsed by the California Board of Barbering and Cosmetology, the Texas Department of Licensing and Regulation (TDLR) or PSI, and it does not guarantee that you will pass. Questions are written by ThiNail from each state's law and general trade knowledge; they are not real exam questions. California's 75% pass mark and the number of choices per question are assumptions, because PSI does not publish them.
