<p>I'm currently freshman in Computer science major and intend to switch to aerospace engineer soon. I really like physics but I wonder if taking the 4 series would be too hard and might pull me back on GPA, (or I might fail those classsssesss O_O and never graduate). So are the 2 and 4 series switchable? </p>
<p>My second concern, maybe too far ahead to think of, is that if its possible to graduate in 3 years in engineering because I have about 36 AP credits but I have been warmed that most engineering students takes more than 4 years to graduate. and If its possible then should I graduate on 3 years or double major, like aerospace and mechanical. </p>
<p>Thank you guys for sharing and everything.</p>
