A job at Infosys is good but everyone cannot secure a big good rank of 23 in TANCET, if you want to utilize your rank you can pursue Mba, also talk with your organisation if they'll sponsor you on a bond or can you 'Learn while you earn'.
You have a very good score so it's your choice between TSM and PSGIM. To be frank Placement in PSGIM is better than TSM, as you have international opportunities in PSGIM. Whereas TSM gives you placement into companies for the intermediate level of the organisation structure.

MAT (Management Aptitude Test)
CAT (Common Admission Test)
CMAT (Common Management Admission Test)
XAT (Xavier Aptitude Test)
GMAT (Graduate Management Aptitude Test Abroad)
SNAP (Symbiosis National Aptitude Test)

Placements in TSM are good but I can't assure you that you may get a better job than what you have been currently placed.In 2016, the average CTC was Rs. 5.7 lakhs and 46% have been placed in marketing, 31% in finance, 13% human resources, 8% operations and 2% business analytics. The highest CTC is Rs. 7.5 lakhs. It's your choice but you will have sweat it out in a residential college for 2 years as the subjects will be more and assignment load is to be delivered effectively.

The difference is the specialisation, the MBA subjects would remain the same however, the final semester subjects would be as per specialisation.

It depends on you that which state or city you prefer to study. There are many private colleges that provide direct admission on the basis of simple entrance or interview.
In Delhi NCR, you can go for:
1.IMS-Ghaziabad
2.IMS-Noida
3.ITS-Ghaziabad
4.ASB-Noida, etc.

Dear Harman,
With this percentage, you can't get admission even in India then why are you thinking for abroad. Kindly go to any low graded private college for MBA and fullfill your dream. 49.6% is too low for MBA. Don't take me wrong. I am not demotivating you but that's the truth!
Good luck!
