<p>I am a sophomore in high school at one of the top 100 schools in Texas. I am number 14 out of 400 (top 3.5%) in my class with a 4.0unweighted and 3.87weighted GPA. I am an active member of ITS (international thespian society/ plan on becoming an officer my junior and/or senior year), have been a lead in 5 plays and 1 musical, I am also part of my high school's varsity theatre program as a sophomore, I am becoming a member of NHS, have at least 100 hours of community service (plan to do a lot more), and take part in my school's science academic competition team. My classes for junior year: AP chem, AP physics 1, PreAP precalculus, PreAP computer science 1, AP US History, AP english III, and two theatre classes. My classes this year were AP biology (90), PreAP chem (93- teacher recruited me for AP chem), AP world history (90), PreAP algebra II (93), PreAP english (90), Spanish III (98- not taking 4), Principals of business (98), theatre production I/varsity theatre (100). And just had a senior friend who got into Stanford and Northwestern. And I went through Duke TIP talent search program and got a 1300 in 7th grade but other than that no. I plan on at least trying to get a 2100-2200 on that and a 30-33 on my ACT. I have shown, I feel, a strong interest in science and math. What are my chances at the top technical school/ biological engineering school (Georgia tech, Emory[sent me emails of interest], MIT, UT[will get in if I stay in top 7%], John's Hopkins, CalTech, and Stanford]?</p>
<p>I am a sophomore trying to get into JHU too. However at this point it is really hard to say wether you will be a competitive application (as is for me) since GPA and scores can change a lot over an year. However what you have so far is good, and rigour of transript is also good (thats one of the main things they look for)
For the rest of this year and next year focus on taking ur ECs to a new level (maybe win some award with the science team or audition for a role in a city production), spend more time volunteering, try to find a hook (maybe try doing a science project for intel or something), and also spend some time studying for SAT IIs and SAT/ACT. ALSO MAKE SURE YOU TRY YOUR HARDEST ON THE ESSAY/ RECOMENDATIONS! Super important!
These things will matter a lot for you since you already clearly display academic exellence.
MIT/CalTech/Stanford is a reach for everyone but if you stay on this path I think you can get into Georgia tech, emory, UT, and JHU. 
Good luck!</p>
