Advice on showing your working in the exam
.1) Mark schemes will normally award marks for showing a method in your spec to solve quadratics. If you just use your calculator to solve the quadratic and write the answer down, the answer MUST be correct, or else you would lose a method mark AND the accuracy mark. My advice is always to write the quadratic formula out (with numbers shown in brackets) to show that you know what to do, but then I would use the calculator solve button to actually give the answer itself as it is more likely to be reliable. (You could always sub your x values back in to check at the end anyway)
2) Critical values. I think as long as you are not USING the fact that e = 1/3 in your justification, then critical values would be fine with a clear rationale at the end as to why it must be > 1/3. If you use e = 1/3 from the start you are not showing, you are VERIFYING, which is not what the question is asking for. It is not usual practice to use critical values for showing e to be within a certain inequality, so some evidence of testing and rationale at the end is important.
Just to reinforce the second point, if you are aiming for an inequality as your last line, then use inequalities throughout your working.
If you use = during your working and then change it to an inequality at the end, the mark scheme can be very unforgiving for the last accuracy mark, regardless of how you test which direction the inequality should go
