I have to write my Plab 2 exam in UK. I don't have any bank balance and properties the only choice i have is applying for the personal loan. I have my booking confirmation for my plab 2 exam and loan approval details from the bank. So is its possible to het UK visitor visa using bank loan. Thank you in advance.
This is a very bad idea and is 100% certain to result in a refusal. You’ll be wasting the £100 application fee, and a refusal on your travel history would make it (much) harder to get a visa in future.
Do yourself a favour, cancel the bank loan and start saving instead (if you can afford to make loan repayments, you can afford to save). Wait at least 6 months and/or until you have a solid financial history before you apply.
As others have commented, there are many questions on this site on the topic, including this one UK visa refusal on V 4.2 a + c (and sometimes 'e') which covers all the key aspects
