## Schedule for GATECSE 2021

The schedule followed by GO for GATE2020

Please do not listen to what random people say about the schedule. This is a relaxed one and so you should not keep any topics for later thinking you have time.

Please see here for GO Book for GATECSE 2020

Advantages of following this schedule:

- It is not the only good schedule possible but is one schedule where subject dependencies are met
- You can ask any doubt from the topics already covered in the schedule here with the tag go-classroom and those will be answered with priority
- Preparation materials including reference links are provided on GO classroom as per the schedule
- Even if you are joining late, you can adjust your schedule accordingly - most assignments in GO classroom will allow late submissions and this schedule will be over by November end.
- Extra points to be followed will be updated here.

I've created a Google Calendar of the above schedule, and it's here. It's useful if you have an android phone, and use calendar, or Google assistant, or chrome browser.
