Good afternoon sir In class 12th I have physical education as my additional subject Can I choose computer science as my subject in CUET UG exam

Ans: HI,
OF COURSE, it is possible to choose Computer Science in the CUET exam even if you had Physical Education as an additional subject in your 12th grade, as long as the university you are applying to for Computer Science or a related course allows it and its admission criteria do not mandate a specific 12th-grade subject.
Candidates can select any subject for the CUET exam, regardless of their 12th-grade subjects, but they must check the specific university's eligibility criteria for their desired course.

ELIGIBILITY CRITERIA: The crucial factor is the eligibility criteria set by your target university for the Computer Science course. Some universities, like Delhi University, have stricter rules about matching CUET subjects to your 12th-grade stream.

WHAT YOU SHOULD DO......
1. Decide on the Computer Science course you wish to study and the universities you want to apply to.
2. Visit the website of your chosen universities and check their CUET eligibility criteria for the Computer Science program
3. Based on the university's requirements, select Computer Science as one of your CUET domain subjects.
4. You can choose up to five subjects from all three sections of the CUET exam, giving you the flexibility to select Computer Science.

If you want to pursue BSc Computer Science through CUET, you will typically need to take Physics, Mathematics (or Applied Mathematics), and either Computer Science or Informatics Practices as your domain subjects, along with any one language subject. It's crucial to check the specific university-wise subject mapping, as eligibility and required subjects can vary between institutions accepting CUET scores.

Ensure you have passed your 10+2 (Class 12) with Physics and Mathematics as mandatory subjects.

I have provided almost all the information you requested. If you need further assistance, kindly reply.

Dentist - Answered on Apr 25, 2026

I have tooth sensitivity when I eat hot soups, cold water or icecreams. I don't have any pain or injury as such. What could be causing it? What should I do? I am 36
Ans: Hello
Tooth sensitivity to hot/cold without pain or injury is not uncommon, even in your 30s.
It’s usually not a major crisis. And it's easily treatable. But it does indicate that the outermost protective layer (ENAMEL) of your teeth is compromised.

LIKELY CAUSES

1. EXPOSED DENTIN: Enamel wears down or gums recede, exposing the inner sensitive dentin.
2. GUM RECESSION : Aggressive brushing, grinding, or gum issues can pull gums back and expose tooth roots. Roots don’t have enamel.
3. ENAMEL EROSION : Acidic foods/drinks, acid reflux, or whitening products can thin enamel over time.
4. CRACKED FILLING or SMALL CAVITY : Might not hurt yet but still lets temperature through.
5. TEETH GRINDING /CLENCHING: Wears enamel and can cause microfractures.
6. RECENT DENTAL WORK: Cleanings, whitening, or fillings can cause temporary sensitivity for weeks.

What you can do right now:

- SWITCH TOOTHPASTE : Use a desensitizing toothpaste with potassium nitrate or stannous fluoride . Takes 2-4 weeks of daily use to really work.
- BRUSH GENTLER : Soft-bristle brush only. No scrubbing. Think "massage," not "scour."
- SKIP ACIDS: Avoid acidic food or beverages.
- FLUORIDE MOUTHWASH: OTC fluoride rinse at night helps strengthen enamel.
- CHECK FOR NIGHT GRINDING : If you wake with a sore jaw, ask your dentist about a night guard.

Red flags to book a dentist's appointment sooner: Sensitivity that lingers >30 sec, one specific tooth that’s way worse, visible gum recession, or if it keeps getting worse despite using desensitizing toothpaste.

A dentist can spot the exact cause and may do: fluoride varnish, bonding over exposed roots, treating gum disease, or replace a leaky filling.
