You should first start with doing a bachelor degree first, here in the post below I've Listed out all the colleges I've found to be worth doing a Physics Bachelors in. https://physicsafterengineering.blogspot.com/2018/09/pursue-bachelors-in-physics-after-12th.html

Types of courses:

Firstly these are the types of courses that are present:

• Bachelors of sciences
• 
  
  • Honors in physics
  • Major in physics
  • General B.Sc
  • 
    
    • The first two are considered equal but Honors degree has a slight edge because more focus is laid in Physics. Also if you are opting for a general B.Sc make sure that you have 4 semesters of physics in your coursework so that you'll be eligible to get admission in IIT through JAM.
• Integrated M.Sc
• 
  
  • B.Sc+M.Sc
  • 
    
    • It's a 5-year course after which you will be receiving both a Bachelor's and a Master's degree in physics.
  • BS-MS
  • 
    
    • This is also a 5-year course similar to above which will be more research-focused and the value of the degree is increasing day by day.
    • IISERs, Few IITs, and IISC, etc offer these programs.

• Engineering Physics, Astronomy, space science or related areas
• 
  
  • Engineering Physics in few IITs
  • Indian Institute of Space Science and Technology(IIST)
  • 
    
    • B.Tech in Aerospace Engineering and ECE(With specialization in Avionics)
    • Dual degree B.Tech+ M.Tech/MSC.
    • You can get a job directly in ISRO after completion of the degree here.
