We didn't win the Intel ISEF. We did win the subject category (Computer Science) in the Indian edition of ISEF, called the Intel Science Talent Discovery Fair, which is a feeder contest to ISEF, back in 2023. I would give a couple of generic suggestions, since most of the other learnings from the process were specific to my subject.One of the most important things is to have a good understanding of the problem that you are trying to solve. Its easy to get lost in the process and not achieve anything. Outline the problem clearly, and set clear objectives. This will go a long way in convincing the judges that there is a real problem worth solving, as well as keep yourself motivated towards the hard goals that you have set.Secondly, keep a log book (we didn't have Evernote back then) of the work that you are doing each day. If you are working in a team, make sure that you work together frequently, and sync up on the progress being made. Often, its not easy to clearly demarcate and divide work, in which case it becomes tricky. Also, when we were working on the project, we had assigned mentors, that we could talk to and discuss our problems with. Their adviceu00a0 and suggestions were valuable. So, make sure you take the advantage of that, if you have that opportunity.
