It depends what you mean, but the short answer is basically: no.
I don't say any of the following to discourage you from putting in a great deal of effort for a short burst of time, but rather to ensure you have a realistic expectation of what is reasonable to learn well in 3 months.
Having 3 months of full time study available to you to work on coding is a phenomenal gift, and frankly I would LOVE such an opportunity. By all means, go for it, but don't be discouraged if you put in all that work and haven't completed the course by the end of it!
Firstly, NO ONE has completed the full course in the 2 years it has been running. So what do you mean by 'complete the full camp'?
You can complete the Front End certificate in three months with 8 hours a day and come away with a pretty decent portfolio of basic front end apps if you work hard at improving. For example, I 'completed' the front end certificate in about 40 days spending about 2-3 hours a day on it. That said, I actually think my current portfolio from that section is of a sufficiently low quality that I wouldn't go showing it to employers until I put a serious amount of work into improving it.
The final certificate can only be started once you have completed the first three. For this one you work with another camper, a project manager and a real life client. Completing those 4 projects with whatever remains of your three months will be impossible.
I would ask what your motivation for this 3 month goal is. Do you have a reason for such a deadline, such as a new term of school starting, or a new position at a job becoming available?
I would also ask what value you perceive there to be in completing the course at all. Do you want to just be able to show people the certificates, or do you want a decent portfolio, or do you want genuine, robust and broad skills in web development? What's your goal? Do you want to get your foot in the door at some little web agency? Do you want to build your own product? Do you want to work for a major tech company?
