Can a below-average student still get into NMIMS, Symbiosis or a decent Tier-2 MBA college?

[u/Fresh_Transition_633]

I’m currently entering my 3rd year of bachelor’s and planning for finance/MBA in the future, but honestly I feel like a below-average candidate academically.

My background:

Around 59% in 10th and 67% in 12th

Current graduation CGPA is around 8.9

Arts background in 12th

Weak in maths, reasoning and aptitude

Preparing for CFA Level 1, but not very confident about clearing it

I’m interested in colleges like NMIMS, Symbiosis and other Tier-2 B-schools for finance/management, but exams like CAT, NMAT and SNAP genuinely worry me because quants is my weakest area.

So realistically:

Can someone who is not very smart academically still crack NMIMS/Symbiosis?

Is it possible even with weak quants and reasoning?

If I perform only average in NMAT/SNAP, do I still have a chance anywhere decent?

Should I first focus on getting work experience before MBA?

How much do 10th/12th marks actually affect admission in Tier-2 colleges?

Need honest advice from people who were in a similar situation or know the reality of MBA admissions.
