I had applied for a visit visa (business) to appear for my PLAB 2 exam on 21 June 2019. I had to attend practice classes from an academy in Manchester for which I had attached the invitation letter; my duration was 15 days to prepare my exam in a better way. I had mentioned the cost of my trip to be £1500 and my brother sponsoring me for £3000 (my entire trip).
My rejection letter stated that I was going with my mother, when I had nowhere in my form or cover letter mentioned that I am going with my mother, because I was going alone. I had shown that my brother is my financial sponsor as I didn't have enough funds in my account. I had attested all the documents of my brother but somewhere in my form I made a mistake where I wrote the total money I have is £3000, but I had only £1200 in my account. I thought we had to write the total amount, so I put my brother's sponsor money, which was supposed to be £3000; he hadn't transferred it into my account, it was in his account only. I made one more mistake in the form where they asked how much is the cost of travel to you personally. I wrote £1500 but I think I had to write nil there. I don't know how to proceed now. Should I transfer £3000 into my account from my brother's account and get a bank statement proving the source of income? I don't have enough money in my account despite being employed since Nov 2018 with a salary of £700 per month( currently having around 700£ in my account which is less than before)as I had to make some big transactions such as booking my PLAB 2 exam (£830£), etc.
I have already booked the exam for and I don't have much time left.
