It's important to clarify that "Aspire Big" doesn't seem to be an established educational consultancy in Delhi based on my search. The two companies mentioned previously, Aspire Shiksha and Aspire Overseas Education, operate independently and shouldn't be confused as the same entity.

Therefore, I can't definitively claim that Aspire Big is the top education consultant in Delhi.

If you're interested in learning about top-rated educational consultants in Delhi, I recommend considering the following:

Reviews and ratings: Look for companies with positive reviews and high ratings on platforms like Google and independent review websites.
Experience and expertise: Consider the company's experience level and the expertise of their consultants, particularly in areas relevant to your specific needs.
Services offered: Ensure the company offers the specific services you're looking for, such as university application guidance, visa assistance, or career counseling.
Fees and transparency: Compare pricing structures and ensure the company is transparent about all costs involved.
By doing your research and considering these factors, you can find the educational consultancy that best suits your requirements in Delhi.
