Hello Abhisek. In my view, if you a slower reader, try to speed up your pace somehow e.g. setting a timer after each question which beeps to you indicating that you should move on to the next question.
This way you might be able to speed yourself up and get used to the quicker rhythm that you should apply on the exam.
Those questions that do require more time - like a critical path question where you have to draw or an EVM where you have to calculate, skip & mark them for later revision when you have some more time left to answer them.
230 mins should be enough for the 180 questions. The exam definitely requires speed and you should apply yourself to it. Try not to spend a lot of time with one question when you don't understand a word. Do not leave any question unanswered! Just guessing is still better than leaving no answer at all. Understand that you won't be able to answer all questions 100% right. Nobody does. Leave yourself a room for some mistakes. This way you will not be panicked. Learn faster reading & understanding & think sensibly which answer is right or wrong (strong coffee, chocolate, walnuts, water can help during the breaks to stimulate your brain).
Sleep well before the exam (do not take it tired!). Also, tell your family to respect your learning time and leave you undisturbed, especially during exam. Do not stress. Lighten up. Be mentally prepared.
This is my advice. Good luck!
