Advice for ENGAA/NSAA/ESAT

Anyone who did good in the ENGAA or NSAA in previous years, do you have any tips because i’ve been trying to do some past questions but i’m also trying to teach myself things from the specification, but i’m not sure what’s the most efficient strategy bc i have sm to do.. should i focus on questions more in the summer or learning the content that i haven’t learnt yet. What’s more important to get a score of around 7.0 or so?
