I have solved some few contests till now and in the last contest which i did after 2 months, i got my first negative rating. I am in college and had to focus on academics for the past 2 months. Now i have 2 months vacation and then internships. So, i aim to reach >1400 to get good internships. Please give me some tips on how to achieve it. There are many students who are in similar situation and this blog might be an important one. So, please give genuine advices on what questions we should solve and contests that we should appear. Also, give any other resources which one can look upto. Should we learn more advanced topics like graphs, trees, and other algorithms or stick to heaps, hashmaps, stacks for 1400. till what questions should we solve in div2, div 3 contests (C in div2, D in div3 or what?). Thank You!! (btw this is my first blog)
