<p>My son also only had 3 years of French. 1st year in 8th grade in middle school, 2 in HS and did not go on in a language. He has 4 years of CAD in HS and is an engineering major. French 4 was honors french in our HS and he really did not want to do it. By not taking the extra language he was able to do AP Calc and AP Physics and a year of programming. </p>
<p>I think if schools see that your son did other things instead of continuing in language they will think it is okay. If you find that he really wants to apply to a school that wants that 4th year in a language, I contacted a couple of schools and they said that while they prefer a 4 th year in the same language, they would accept a 4th in another.</p>
