JEE

Yes, you can join ISRO without JEE Exam because you need to first have a BE or B.Tech or equivalent qualifying degree. ISRO conducts its written exam first which you can only apply if you meet the academic qualification: Students must have qualified B.E/B.Tech with a minimum of 65 percent. Indian Space Research organisation offers jobs for only specific branches. Some of them are Electronics and Communication Engineering, Electrical Engineering, Computer Science and Engineering, Mechanical Engineering, etc. You need a degree from any good and a reputed college is also sufficient. Candidates pursuing B.Sc. Courses can also be eligible, right after they complete their Master's in the fields of Agriculture, Mathematics, etc. For direct recruitment in ISRO, candidates need to require a GATE scorecard. Students who score well in the GATE exam are direct selected by the Indian Space Research organisation. However, the crowd gets reduced further because there is one final test given by the Indian Space Research organisation itself which tests the intellect and knowledge of the candidates applying, From them, few are selected for jobs, internships, or even training in the Indian Space Research organisation. I hope this will help you.

175 isn't a good score if you want CSE in top colleges. You surely need 200+ and much precisely 220 because there is no board percentage. So this time we can't say what's gonna happen. Everything will be changed. By this year's JEE Main we can predict next year results. So if you really wish to be in a top college and CSE then 220 is needed. I can simply give one tip to you. Know how to pick your answers. AJEE Main paper will be moderate. Expect 11 easy questions 12 to 14 moderate and 5 hard. Leave 5 hard but solve easy and moderate surely. Make sure that you solve 20 from each subject. And Bro, let me say you time is important. Chemistry can be done in 30 minutes. And keep 1 hour for a subject maximum and bubble instantly so you won't lose any time and no mistake will happen. So, I am saying the above words seriously because I've done that mistake and left many questions which I could have easily solved.

First of all, I would congratulate you for getting a good rank in JEE Mains. Well, there seems to be a slight miss-match with the general trend of ratio between OBC Rank 1338 to General Rank 48k but According to your data if the OBC Rank 1338 You can get top branches like CSE, ECE, EEE in top 7 NITs like VNIT, NITC, NITW, NITRKL, NITK or MNIT which is a very good thing! Whereas it might be slightly difficult to get CSE branch in NIT-Trichy as CSE branch in NIT-Trichy has the highest cutoff amongst all NITs but you can still aim for CSE Branch in any of these 7 NITs (except for NIT-Trichy). Now talking about IITs, you need to provide your JEE Advanced Rank as JEE Mains Score cannot give you admission to IITs. So with this rank, You have very high chances of getting all top branches like CSE, ECE or EEE in top NITs. Good Luck for your Counselling!
