Hi guys! I'm new Rohit and I'm new here

I am assuming your from the uk as youre doing a-levels. if you want to do physics you need to take maths, physics and preferably (but not essential but will make your application more competitive) further maths, the other subject you take doesnt matter. The entry grades for physics range wildly from needing BCC to A*A*A* at A-level dependent on where you want to go (you will need to look into this). Outside of the top 4/5 UK unis, gcses dont matter too much but you will need at least passes in science, maths and english plus a few others.

As for which physics course, I recommend taking MPhys Physics if your interests lie in just physics. There are some joint honors courses but not many (this is where you study 2 subjects at university, most common is maths and physics (this is essentially what I do))

While I dont recommend using league tables much when deciding a university, a good rule of thumb is the higher up the league tables you go the more advanced content in later years you study (but the difference between say 10th and 15th will be little, I mean when you compare 5th to say 25th)

 

Well if you want to go be a physicist and work in astrophysics etc then you need a undergraduate degree in physics not engineering, if you want to work in automobile engineering then I would imagine a mechanical engineering degree would be required.

The MPhys course is a 4 year undergraduate course so the first 3 years are the same as the bachelors course and you do an additional 4th year which is designed for people which want to go onto a phd (this is not the same as a postgraduate masters degree which is what you are talking about)

To go into astrophysics you would need to do an undergraduate degree in physics (either Bsc pr mphys but preferably the latter) then go onto do a phd in an area of astrophysics (you need a undergrad in physics as this provides the foundations for more advanced studies in a specialized area) then you can apply for post doc jobs and do research in astrophysics and then if youre good + bit lucky you get a fellowship then university position conducting research and lecturing

I did say before for physics you need to study maths and physics at A-level and preferably but not required further maths then another subject of your choosing (it doesnt really matter)

You do NOT want to do a mechanical engineering degree for going into physics, you want to do a physics degree then a phd

If youre interested in engineering at university then you will still need to do maths and phyiscs at A-level + another 2 of your choice. But you wont get into astrophysics by doing a mechanical engineering degree as a post grad masters is normally not enough you need an undergraduate degree in physics.
