I want to learn DSA and do Leetcode but I'm confused where to start

Currently in 1st year, I have completed basic c++, all the loops and c style arrays and stuff like that, now I'm confused how to proceed, I open up a leetcode problem and there is time and memory and all that stuff and I don't know how to deal with it, there is also the weird thing of class stuff that should be at the beginning of each question, I don't know where to learn all of this.

Can someone suggest where to learn all of this, because I couldn't find a proper series that teaches all of this. Also tell me what things I should learn before I start doing leetcode, I have already started learning STL, is there anything else I should learn?

Since everyone is getting their refunds I want to share something interesting that happened to me

I did accept a collage through CSAB, and that is why I think what happened to me doesn't make sense.

First here is a timeline of all the payments I did:

30k at the beginning of JoSAA

I got a seat in JoSAA and then withdrew

Decided I wanted to participate in CSAB, so paid 17k at the begging of CSAB
Paid 35k after I got a seat in 1st round

Now the weird thing is that I got a refund of 23k from JoSAA about a month and a half ago(around mid august)

And this is the thing that dosen't make sense to me, why did I get a refund if I accepted the collage??

Has this happened to anyone else??

Only a few hours left before choice locking, please tell me if I should add or rearrange something.

I have 44k crl and 6.1k EWS rank.
Preferences:
I prefer CS specializations above core CS and MnC above all that.
I don't mind going into core EE for NITs but opinions on this are appreciated.
I'm from Gujarat and would prefer to stay here, but I also don't mind going to the neighboring states(MP, Maharashtra, rajasthan) if I have to

BITS Hyd MSc Chem vs Nirma University CSE/ECE

For 5 years bits fees are almost 40 lakhs and nirma is 16 lakhs, I'll have to take a loan for both of them. For those who don't know Nirma is in Gujarat and has a decent reputation, CSE cut off for it is 45k. I have 44k in mains and 203 in BITSAT. Also yes I might get some IIITs or NITs but I don't wanna go to them as either they are really far away or not that great

Please tell me the new mathongo mocks are harder than session 1.

Especially the ones after 20 are tough as shit, like I was scoring above 200 in the 15-20 fts (except 19), but for the ones after 20, it's all shit, I haven't crossed 200 in any of them. Physics is the biggest downgrade in marks, before 19 I had an average of 45 in physics and after that average of 30 with lowest of 22 like I consider myself decent in physics, I have almost all of syllabus covered in it and I'm not able to solve so many questions. Eng/LR and math are the only ones I'm scoring above 50 and 60 consistently.

Do I put physics above nanoscience, if I'm more intrested in physics?

I know people will say just go and study and do this after second session but I was just doing this when I was taking a break. I have heard on BITSPilani subreddit that nanoscience is just mostly chemistry, I'd prefer if I don't have to study chemistry and I'm more interested in physics anyways but if nanoscience does really help with ECE than I will put it above physics.
Also just don't ask my marks in session 1

Background: 12thie, got 97.2 percentile in S2, now preparing for BITSAT.
Some people might consider this a good percentile but I feel it isn't enough for me. Currently I'm getting a good tier 2 collage in my state(Gujarat), Nirma University. If BITSAT dosen't go well I want to take a partial drop. I want to study mainly for advance in that time and give jee mocks in Jan, if any partial droppers are reading this please guide me. I want my primary target to be advance so that I can fulfill the IIT dream that I failed at.

I also can't take a full drop since I know I will not study(I have not been seriously studying since last 2 months), a change of environment would greatly help

18M, 3-4 years ago I used to watch 20 episodes in one day, now I can hardly watch one episode in a week. It's not that other things in life are not allowing me, sure I have less free time than back then but I still have 3-4 hours a day free, but I spend it on reddit or some shit. I have 200+ anime on my to watch list, I really want to watch anime but just can't sit through an episode. Sometimes I watch in small bursts, like I binged both apothecary diaries in a week around a year ago and I binged first two parts of JoJo's a few months back, but beside this, I can't keep up with the weekly stuff and I really want to. If someone has gone through a similar situation then please help me

I have seen people saying that CSAB is luck based, like for some IIITs I'm interested in, I do fall in the rank range of students admitted in 2025. I have 44200 rank, can I get IIIT Vadodara ECE? Generally, what would be safe rank compared to 2025 for any IIIT/NIT through CSAB?

I have 97.2 percentile (44k rank), I have researched my options through JOSAA and none of them are appealing. Currently I am considering LNMIIT and Nirma University, I have chances of getting CSE(AI/ML) at both collages. Main concern is fees, Nirma has 3 LPA fees (excluding hostel), while LNMIIT has almost double. Placements of LNMIIT are clearly better but my parents are concerned about fees

It says here that total 54 students got placed and I read on the placement brochure that batch strength is 142(2nd image), is there a reason behind low placement that isn't visible in pure data? I am asking because I am considering joining mechanical

The bitsat website is acting really weird for me because whenever I open it, it only sometimes shows all the posts and most of the time, no posts are visible. It says here that application forms have started from 27th April, but I can't see them anywhere
