Look at what the LOS says! Do you have to calculate something (like a confidence interval) or just be able to discuss it (kurtosis). No need in over doing it...you've got plenty else to worry about.
Also, there's a 0.0001% chance you'll actually remember everything in Quant the first time through so don't kill yourself on it right now. Just focus on understanding it now and aim for mastery with the reviews and lots and lots of practice questions. Some people may disagree with that but it's a less stressful way to approach it.
