Under Improve rs_series, you need to provide some idea of how you plan to implement at least a couple of those new rs_series functions that you suggest. Maybe you could implement one of the comparatively simpler ones and send a PR for it.
Also you mentioned: > I want to add more methods to ring_series so that its implementation is more smooth,fast and efficient. You need to clarify this point a lot more. Which parts of the current implementation need improving and how do you plan to go about doing over the summer. What gets more preference, improving the current implementation of existing functions or implementing new ones ? Ditto for the other sections as well. In the Timeline, you should provide a proper breakup of the tasks in the proposal and fairly appraise the time required for each. Most people provide a Week-wise breakup of the summer.
