It took so long for me to become a pupil. How can I grow faster, and which topics must I cover as a pupil?

How to be speed and how to get better sleep schedule
Any specific topic that helped you most on this journey?
No, as you see, I dropped back down :)
1 Huge thing on CodeForces is speed. Make sure to sharpening your instinct and cutting edge thoughts about edge cases (I'm still getting trapped everyday and got slowed down... sadge)
I'm also facing this problem. So many thoughts run on my mind while solving.
I'm from Bangladesh. These contests held at 8:35 p.m. in Bangladeshi time. So I've got no problem with my sleep schedule.
lack of sleep hampers cognitive function. it doesnt have anything to do with what time you give contests
I didn't sleep last night & today is div 3. (:_
gl man
it can't be... RED0, my predecessor
alt account?
lol not my alt :)
worked for me
Thanks. Any specific topic that helped you most on this journey?
greedy and brute force, for pattern recognition
implementation to manifest my ideas into code
Thanks for your time.
Bhai Bangladesh e situation thanda hoyeche ?
Hae. Aste aste thanda hocche. Internal onek politics ache. Hope it'll get better soon.
I would suggest Bit masking
Thanks. I learned a little of this topic but didn't solve much problem.
Disagree.
solve problems of rating 1300-1500, try solving C of every div2 and upto D-E of div3 and stop solving those 800 rated now
Ohh Thanks. Last few contests I solved C in div 2. But it isn't consistent.
yeah same here, i am also on my grind to reach specialist. All the best, we will reach there !!
Hope you get some positive delta in today's contest.
Adding you to friends.
orz sir atb you will reach spec ez pz
there really arent any specific topics, you just have to solve div2 ABC decently fast, which usually doesnt require any advanced topics. sometimes graphs or trees show up at C, and rarely DP but generally, its just regular problems that dont require advanced techniques.
tldr: just solve more problems
Ohh thanks. Solved ABC in last few contests but it isn't consistent. Hope to be consistent.
If your goal is to reach specialist, there is no need to go topic hunting.
Just practice a lot of binary search problems learn basic math algorithms like sieve, mod arithmetic, gcd, divisors and prime factorization, understand basic bitwise operations. Basic dp would also help in some dic 2c and div3e problems, although not essential.
To sum up, just focus on your speed and practice greedy and basic math problems. Also I would suggest to focus more on div 3 and div 4 to gain speed and greedy problems intuition.
Ohh Thanks for you time.
Is it possible to reach Expert with just solving A and B in div. 2 or div. 3? My first attempt in Codeforces long ago was very bad, but I’m thinking about coming back.
I think not.
I can tell u practices that I am doing if u want. I changed my strategy and it's working good
Do tell please. Kinda hard stuck on 1200-1300, what rating range and topics should I practice to make the jump to specialist? Should I put more focus on speed or quality of problems? What strategies helped you?
Don't practice by topic.
Thanks for your advice.
FFT
Ig Binary Search on Answer and Variable Size Sliding Window is good to go for most of div 2Cs (currently strengthening them and I can notice better strike rate at 2Cs)
Ohh that's great.
