I am currently left with time series chapters to finish the course.. I am wondering what is the importance of Q/A bank.. I did the same for part 2 and part 3 and now i am confused whether to spend any more time on them or proceed with the course and past papers.. PS: I haven't yet touched the past papers. Any comments and suggestions will be appreciated. Thanks!
Its really down to personal preference, but what is always paramount is that you go into the exam having completed the course so don't let Q&A get in the way of that. Q&A may not be in the same level as exam questions so the best simulation of exam day will be past papers done under full conditions. Q&A can be used to check your knowledge quickly or give you 'rapid fire' type work if you only have a relatively short time to revise. So my attack would be Complete the course Some Q&A to check for weaknesses by topic Lots of past papers under timed conditions. Also make sure you write your answers.... don't just think yes I know that.
