I am planning to apply for plab 2 visa

Hi,
I am planning to apply for plab 2 visa in 2 months and have some queries regarding it…
1- i started specialty training (work) a month ago but i won’t get the salaries of the first 6 months until September. Anyway my salary is too small (like 70 dollars/month). However, my parents gave me good amount of money a year ago which is more than enough to cover all the expenses (x 3) for a 3 months trip to England. I put that money as a DEPOSIT in my name… so the bank statement is going to be in my name, do I need a sponsor in that case? Or it is better for my dad to be a sponsor in addition to my bank statement. Also, should I clarify where i got the money from? If yes, how (a signed paper from my father is enough)?

2- A non-objection paper from my hospital is all what I need from my employer? Any additional papers that could make my case stronger? Annual leave maybe or is it the same of the non-objection paper?

3- my parents lands are also important right?

Thank you
