My PLAB 1 Experience
I prepared for around 3-4 weeks for this exam. Mind you that it was not full time prep. I was an intern then.
On the day of the exam, I was surprisingly calm. We were offered coffee/tea and biscuits before proceeding for the ID check.
The exam is easy. Time is the essence. I finished my first round in 2 hours and planned to use the last 1 hour to revise all the questions. However, I could not revise the last 25 questions.
Also remember that many questions might have the same answer. In my test, the answer to around 6-7 questions was ‘normal saline’ and I started to panic, although I knew that it was the correct answer 
Be calm. You will ace this exam
