Dear
nnvin,
The decision to apply to R3 should be taken independent of conversion numbers.
Note that while 20% of the entire cohort is filled from R3, the number of applicants who have applied in R2 and R1 are also significantly higher compared to R3. Hence, you should make the choice based on the following factors and not just the absolute no. of people selected.
a. Do you think you can demonstrate quality in your experiences and profile by R3 deadline?
b. Do you think you have / will have a competitive GMAT score by R3 deadline?
c. Do you think the incremental value add to your profile in 9 months (considering you will apply in R1 next year i.e Oct) is not significant enough and you potentially have most of the skillsets even if you apply now and not wait three more quarters?
I am an ISB alum and have been guiding applicants in their admission journeys for last 6+ years. Feel free to set up a pro-bono profile evaluation and admission chances session with us in case you seek further inputs to make a decision.
Cheers and all the best!
