Will this be okay?
Yes, I think that sounds good. Note, as I said in reply to some other queries about GSOC exactly what you would or wouldn't achieve within the duration of the project is less important than demonstrating that you are capable of making significant contributions to SymPy. All tasks can turn out to be harder or easier than expected so it's hard to estimate in advance what is possible given a fixed timeframe. When reviewing GSOC applications (just speaking for myself - I am not the only reviewer) I am most interested in ensuring that we can get the best contributors who are capable of making the most valuable contributions to important parts of SymPy. What you are proposing here is a significant improvement to an important part of SymPy so the main points to focus on in your application are: 1) making it clear why this is important and how significant the improvement is 2) demonstrating that you personally understand what needs doing and are capable of doing the necessary work Then if your application is successful and it turns out that (based on the work you have already done) it is not hard to complete some of the tasks listed then there is no shortage of other things to be done for ODEs in SymPy. On the other hand if one of the tasks turns out to be more involved than expected then it is better to limit the scope of the project later and make sure that the parts that are implemented are done well. A general point that I often make to students is that (usually) it is better to do half a job well than to do the whole job badly. If half a job is done well then it makes a good starting point for someone in future to finish that work. If the whole job is done badly it potentially makes it more difficult for someone else to improve that work than it would be for them if starting from scratch.
