Up to what extent can a student's prep for a high ACT score help him get a high score on the SAT?

Asking this for a friend of mine who scored a 35 composite on the April ACT. He doesn’t have much ECs so to strengthen his application he is considering taking the SAT too. How much do you think he’ll be benefited by his ACT prep?

waste of time, dont take.

Agree with bthunder - a complete waste of time. College admissions committees are looking at a lot of things in the application. First and foremost strength of class schedule and GPA. They want to read a compelling, revealing essay in the applicant’s voice. They will look at either the SAT or the ACT. A 35 on the ACT is great. Your friend is done with the standardized test. Prepping to take the SAT means your friend is not doing something more interesting.

@Luharnos I concur with both bloodythunder and glido. His standardized testing is done, unless he considers taking SAT II Subject Tests which might give him a bit of an advantage. As long as his GPA is fine, I recommend he shows leadership by joining school clubs, being involved and the like. Also if he has any idea where he feels like attending college and if you could supply his gpa and amount of EC’s that’d be easy for us to evaluate him. If however, you’re only concerned about him taking the SAT, then the answer is no, it will not be fruitful for him. He should invest his time in EC’s and bringing his GPA up then worry too much about SAT. A 35 on the ACT is excellent anyways.

I would work on SAT subject tests. If you have 35 on the ACT, you should be applying to schools that require or “recommend” SAT IIs.

The only possible reason I could imagine taking the SAT is if he needs a confirming SAT score for Nat’l Merit SF status. If his PSAT score is at or above the NMSF cutoff level for his state, he will need to score approximately 1970 on the SAT as a confirming score.
