im starting my prep from today any advice ?

these are some advices that you can follow:
1. do not try to cover all the topics since there is not much tme left. go for arithmetic and algebra and if you can not cover them all then choose most imp topics from them.
2. as for varc watch videos of different types of questions asked in rcs and jump straight into solving rcs and va question same goes for dilr understand the topic once and try solving set.
3. give mocks and sectionals and recognise your strength and weaknesses. work on your strengths and try to polish them.
hope this helps you can ask if you have any doubts.
as for the videos to follow you can go for mba wallah's videos their teaching style is really good

Can anyone suggest any good playlist for DILR. It was my weaken area.

start with arithmetic in quant since it's the highest weightage, read 1-2 RCs daily and do a few DILR sets every week. once basics are done start mocks, consistency matters more than hours. all the best!
