Question by Pradip - Mar 17, 2023Hindi

Health

If I wake up after 4 - 5 hours of sleep for going to the toilet or feeling cold or any other reason or for apparently no reason, I can't get back to sleep. I can go to sleep again if I have had 3 hours or less of sleep. I can work if I get up but after completing breakfast at around 8 AM, I have to take to bed. Even then, I can't always sleep. My head aches severely without 7.5 to 8 hours of sleep, the extent of severity depending on the extent of sleep shortage; I also get irascible, my eyes irritate and I make wrong decisions. Incidentally, I am 59, am suffering from IBD, have high myopia and glaucoma but no other serious diseases. If I get to sleep 8 hours a day, I can work as well as I did when I was 25 years old and better than and more than most 25 year olds. However, I get this sleep only 2 - 3 days a year; the result is low productivity.

Ans: This is what many sleep experts advise- Stop watching the clock when you are trying to go back to sleep, this will make you more anxious..
Tense each muscle group (starting from the toes upwards) for five seconds, then relax.
If you can’t fall back to sleep after approximately 15 to 20 minutes, get out of bed and find something boring to do and go back to sleep when you feel sleepy again.

Try to go to sleep and wake up at the sametime everyday — even on weekends and holidays.
Avoid consuming caffeine at least 6 hrs before bedtime. .
Make your sleeping environment comfortable.
One hour before bedtime, stop doing work or other mentally-challenging tasks.
Use your bed only for sleep or intimacy. .

As a last resort you can try using Melatonin gummies

I took pcb in 12 along with Artifical intelligence . how can i take cs in btech

Ans: Hi
You can take B.Tech in Computer Science even after PCB + Artificial Intelligence, but the path is a little different because Mathematics is compulsory for regular B.Tech CS in most colleges. Clear Mathematics via NIOS (or CBSE Private) but it will not be possible at IITs, NITs, IIITs require Maths in regular 12th, so they remain closed.

You can appear 12th from the other board.

College m kisi exam m lge ufm ka hmare future ke kisi bhi exam m chahe competative ho ya fr koi or university ki uska kya prabhav pdta h

Ans: If UFM (unfair means) is recorded in a college exam, it can negatively affect your future exams only if it appears on official records or transcripts; otherwise, most competitive exams and other universities do not consider it. It is better to stay cool, calm, and quiet and focus on the course for which a student is preparing.

Good luck.

Question by Khushi - Dec 23, 2025Hindi

Career

Sir, I passed my Class 12th in the 2023–24 session with very low marks because at that time I did not know about JEE. After that, for two years I worked in the finance field with my uncle. Later, due to my interest in engineering, I wanted to get admission to a good engineering college. That is when I came to know about IIT JEE 2026. When I checked the JEE eligibility criteria, I saw the 75% requirement, but because my health was not good during my board exams, my marks were very low. So, I am reappearing for Class 12th in the 2025–26 session. My question is: will I be eligible to appear for JEE Advanced?

Ans: No. You are not eligible for JEE (Adv). You have already used two attempts (i.e., 2024 and 2025), whether or not you appeared does not matter. Only two successive attempts are allowed for a candidate who clears the 12th grade in a particular year. You cleared your 12th grade in 2024.

Suggestion- Instead of running behind JEE exams, take admission to any good engineering college via a state-level engineering entrance test, which is easier than JEE.

Good luck.

Financial Planner, MF and Insurance Expert - Answered on Dec 23, 2025

Asked by Anonymous - Dec 02, 2025Hindi

Money

I am a retired person 65 years. Sold a property . After paying LTCG tax , I will have 1.25 Cr to invest. Q1 - Should I pay LTCG tax and invest balance or avail 54c limit of 50 lakhs and invest balance. Q2- Pls suggest investment so that I get 1lakh per month.

Ans: For your question no. 1 please consult a tax consultant or a Chartered Accountant. Regarding earning Rs 1 L per month, you may need to contact a Certified Financial Planner and/or Certified Investment Adviser as at present it is not feasible to earn Rs 1 L per month on your proposed investment from the Fixed Income Instruments like Bank FDs. Therefore you need to plan and look for other investment options like Mutual Fund etc, however you should note that MF Investments are subject to market risks etc.
Best wishes.

Sir, My age is 45 now. I want to shift my career into IT. what can be done. Also want to retire in 53 age. Salary gross 95500 INR . May I choose mutual fund sip but in whose sip? Sbi, ICICI ?

Ans: About your shifting the job, I am not the right person to guide you. However as you wish to retire after 8 years, it can be discussed with a certified financial planner after taking all the required input about your past investments, present status of such investments, your life goals and prospects of increase in your incomes going forward. Choosing a mutual fund will come after having completed that exercise. SBI & ICICI are definitely bigger mutual fund companies but there are around 45 MF companies at present in India.
