1. Will answers be considered if I don't round the calculated answer to the nearest decimal places? And will it be correct if the answer I got and the answer on the marking scheme are same but not rounded to nearest decimal places?
For example:
I got the answer to a question that is 0.042
Marking Scheme answer is 0.0419 Or vice - versa.

If it's not specified, there should be no problem.

And don't round answers in the middle of questions, Well to a certain degree you can but keep the full answer stored in calculator.

Yes, good point. It's good to get into the habit of keeping your answers in an exact form until the final answer, otherwise you run the risk of following a correct method, but obtaining a completely different answer due to premature rounding.

You might be penalised for this. Most maths exam papers have instructions on the front cover which say that, unless otherwise stated, numerical answers should be given to three significant figures. 0.042 is only two significant figures.

Sometimes this would lose a mark, sometimes not. If the mark scheme has a comment of CAO, that means correct answer only, which includes the correct number of significant figures.
