Hi Nimesh. As the questions stands currently, it lacks details due to the following reasons:

• We do not know as to where you are from. 
• We don't know what college you are talking about. 
• We don't know as to which entrance exam you are currently preparing for. 
• We don't know as to whether the 150 means your rank or your marks.

Hope you get back to us ASAP and all the best! 

Will you please mention the exam that you're aasking about? As there are many entrance examinations, I cannot answer your query .

Without knowing about which exam you are talking about how can we answer your query.

Please provide your detailed question we will be happy to help you out.

All the very best and good luck.
