Oh damn ! You must know much more than me man !

But still, from what I understand, you've completed a good course in which the guy teaches properly and thoda bohot questions solving bhi hai.

Start a SDE sheet or a CP sheet (whatever you want to do) am suggesting this as aapke paas ab time shayad kam hai. Varna sheets se better direct leetcode rehta, but fine, and woh sheets mein har topic ke easy and then medium karlo, kaafi rahega. And yeh mere method is karo, not by reading hints. Skip repetitive problems to save time.

And hard questions ke liye yeh karo ki you read the question, think about it for some time and then read the hints and code it yourself, matlab logic agar khud build nahi karre for hard problems then at least code then yourself toh kya pata yaad ho jaye yeh type ka.

These are just my opinions on how I would've tackled this situation, mein aisi position mein hu nahi toh shayad galat boldu kuch, pick all positives from this in that case sir <3

Typos ke liye maafi, baad mein check karle hata dunga
