I want t change as medical student advise

What do you wanna change? You wanna change your stream or you wanna change your study field? What do you wanna change isn't clear from your question.

The advise which you should focus, is that what ever you want to do be sure that you are interested in it and also the stream you want to focus on, is capable to fulfil your dreams. Based on your aspiration and your capability choose the field and you will suceed.

I would recommend you to repost the question more elaborately so that we can understand what you wanna change and can provide you all the information required as soon as possible.

Have a great day!
