Asked to add the confirmed password code in student registration page.

Times asked 1
Official solution

SimpleLive Flask coding: chhota route likho, save, browser/curl se test. Syntax error terminal mein padho.
Example
```
@app.route('/ping')
def ping():
    return jsonify(ok=True)

@app.route('/even/<int:n>')
def even(n):
    return 'even' if n % 2 == 0 else 'odd'
```
5
What is POST, PUT and PATCH ?

Times asked 1
Official solution

SimplePOST naya janam (har baar naya id). PUT poori photo replace. PATCH sticker chipkao.
POST create, not idempotent. PUT full update, idempotent. PATCH partial.
POST ki jagah PUT se REST semantics toot. GET typically no body.
CRUD map: POST create, GET read, PUT/PATCH update, DELETE delete.
Pehle 1-line definition, phir related MAD2 layer (Vue SFC / Flask route / models.py / tasks.py / Redis).
4-line formula: input kahan se aaya, auth/validation kaunsa, DB ya cache ya Celery, kya return.
Related mix mat karo — cache ≠ Celery, authentication ≠ authorization, v-if ≠ v-show, Beat ≠ Worker. Follow-up ke liye ek difference ready rakho.
Example
```
POST /api/venues
PUT  /api/venues/1   {all fields}
PATCH /api/venues/1 {only name}
```
Project example: POST /api/venues create. PUT /venues/1 saari fields. PATCH sirf name.

Advice: Proctor was good and helped me to understand the question he asked by commenting in the GMeet chatbox. And I can able to answer well. Some questions I don't answer properly but sir understood. Level2 Viva went well. So, be thorough with your app.py coding in your project and answer well. Just look for common questions in previous term viva questions and go through your project coding which will be asked in Level2 viva. Be patient and don't get nervous in Level2 as it is important.

SimpleSQLite file-based chhota DB, MySQL/Postgres server-based production DB.

At the end, I asked for feedback and what I could improve for Level 2. He said I should just go through the project again, and everything is fine,I’m good to go for Level 2.

Times asked 1

Official solution

SimpleImprove ideas: caching, better validation, tests, pagination, email reminders, accessibility, mobile UI, logging.
Viva tip1-2 concrete features bolo jo time milne pe add karte — vague 'AI' mat.

Advice: He is a quiet person. Initially, you may feel like you’re talking to yourself, but after the demonstration, you will get used to it. Just maintain complete focus on app.py and its relationship with models.py. Also, practice some basic routes and Jinja loops. If you are confident with your app.py code and have covered all the points mentioned in the rubrics, you can score good marks with this proctor.

Advice: My viva was supposed to be at 10am, I had joined at 10, then at 10 15 another person(not the proctor) joined and told me that the examiner is not available and will join at 7pm, I agreed and joined at 7pm then the same person joined and told me to wait till 7:30, then the proctor finally joined at 7:30. The viva lasted till 8:30. One thing to note is there will be a lot of disturbance in the background when the proctor is unmuted. He will give a lot of feedback and changes that you can make to the project.

Syntax mistakes are maybe okay hopefully cz I did but she WILL correct you and ask you to redo it properly. Having a commands txt file is allowed and saves time (I had for venv pip install n all and data for registering company,creating drive to save time). (but that saved too much time so she got lots of time to question lol)
