SUMMARY

The discussion centers on the age at which one can start a PhD in Physics, specifically addressing concerns from a 21-year-old prospective student. Participants unanimously agree that age should not be a barrier to pursuing advanced degrees, emphasizing that many students begin their PhDs in their early twenties. The importance of strong mathematical skills is highlighted, with references to studying materials such as Poole's Linear Algebra and Larson's Calculus. Overall, the consensus is that a 21-year-old is well within the typical age range for entering graduate studies.

PREREQUISITES
  • Understanding of A-Level qualifications in the UK education system
  • Familiarity with advanced mathematics, including Linear Algebra and Calculus
  • Knowledge of the typical educational pathway for Physics PhDs
  • Awareness of the admissions process for top universities
NEXT STEPS
  • Research the requirements for A-Level Mathematics and Further Mathematics
  • Explore the admissions criteria for top UK universities offering Physics PhDs
  • Study Poole's Linear Algebra and Larson's Calculus for foundational math skills
  • Connect with academic advisors for personalized guidance on graduate school applications
USEFUL FOR

Prospective physics graduate students, academic advisors, and anyone considering a non-traditional path to advanced education in the sciences.

I recently moved back to the UK, but since I haven't been in the UK for the past 3 years, I will have to wait for 3 years to do an undergraduate degree. What's even more, my high school diploma, which is from Egypt, is not accepted to be equivalent to the British A-Levels, and so I am doing A levels at the moment. However, by the time I can apply to universities, I will be 20 or 21 depending on certain circumstances. Do you think my age will affect my chances if I apply to top universities? From a general perspective, do you think I will be expected to be better than the average 18 year old applicant, since I had two more years to be better or something?

No it's not too old and actually it's never too old.

The real question is how much math do you have under your belt for physics?

If you get a BS and then wait ten years before going to grad school then you'll have to recover your math edge, a problem younger BS students fresh from the undergrad won't have to do,
 
I have been recently reading Poole's linear algebra and Larson's calculus. My math skills are alright. + I am doing an A-Level in mathematics at the moment, and even if I do take a gap year, I will be doing a Further maths A-Level.
 
So if you're doing okay then talk with your advisors about your plans and they can provide more accurate information about getting into a top flight school. Even if they say no then still apply because you can't win if you don't play the game.
 
Here people are 19 or 20 when they start their 5 year road to an MSc. Throw in a year delay and the average student is 27 when they start their PhD. Donno what you are thinking.

Where exactly is here?
 
Plenty of students start a PhD later than that. I'm 28 and in my sophomore year of undergrad. I'll be starting a PhD when I'm 30 or so.

Netherlands. Ok, there are also people that are 18 and have no delay. It's a 3 year BSc and a two year MSc then a 4 year job as a research assistant/teaching assistant while you do your PhD research. Maybe you have to say that they are 21-23 when they enter grad school.

Just confused that you think you are way too old at 20 to start a PhD. If you had typed '23' I would be 90% sure you had meant '32'.
 
I hope not, I'm in my early 30s and in my first year of physics grad school.

21-22 is when most people start physics PhD's seeing as how they graduate undegrad by then, most physicists are NOT a Julian Schwinger who finish their PhD's at age 21 and are doing pioneering work by age 25.

I think he meant starting his undergrad at 21, and then progress to a PhD.

how I envy the young, yes you :wink:

I have 5 years of study to do before I can even think of school then it's 12 years of school :eek:

I've heard a lot of people talk about how math and physics are a young person's game. They say this because typically the people who make grand innovations in our understanding of their fields do so before they're 30. But, there's plenty of people who are well into their 70's who are still doing great science and making progress in their fields. And 21 is definitely still a safe bet. If you were 35 as a first year undergrad and had to worry about holding a job while you work and kids and all the mess that comes with that age, you might have a problem. but even then a responsible person could still do it.

TLDR; You'll be fine :D

A 21 year old is a child in a man's body.

There is no age limit to getting an advanced degree. If you were 60 I would say go for it. If you were 80 I would say go for it.

Contrary to younger peoples beliefs, you aren't actually dead past the age of 30. In fact I went back for my bachelors degree at that age.
